Conclusion<\/a><\/li>\n<\/ul>\n<\/div>\n<h2 id=\"tg263-linguagem-comum\">TG-263 and the common language of radiation therapy<\/h2>\n<p>A medical physicist receives a treatment plan exported from another institution. Upon opening the DICOM file, the left parotid is labeled <span class=\"tg263-code\">Lt Parotid<\/span>. In the next case, from the same center, the name appears as <span class=\"tg263-code\">PAROTID_L<\/span>. A third patient shows <span class=\"tg263-code\">parotid_left<\/span>. And in the receiving department&#8217;s own template, the same structure is listed as <span class=\"tg263-code\">L_Parotid_Gland<\/span>. Five different names for the same organ at risk, within a relatively small universe of cases.<\/p>\n<p>This scenario is not hypothetical. It reproduces real data collected by the AAPM prior to the publication of TG-263. Across 20 surveyed institutions, the task group found between 21 and 311 defined structure names, with variations ranging from personal abbreviations to entire conventions created by a single professional and never formally documented.<\/p>\n<p>The problem seems minor when viewed in isolation. But it accumulates fast. When a department tries to automate DVH review, train an auto-segmentation model, consolidate data for a multicenter study, or simply compare plans across patients treated in different years, the lack of standardization becomes constant rework. Every analysis requires a preliminary &#8220;translation&#8221; step that consumes time, introduces errors, and prevents real automation.<\/p>\n<p>The AAPM recognized this bottleneck and, in 2012, established Task Group 263 with a clear mandate: create a nomenclature standard for anatomical structures, target volumes, and DVH metrics that could be adopted by any radiation therapy department, regardless of vendor, country, or operational scale. The group brought together 57 participants &mdash; 33 clinical physicists, 15 radiation oncologists, 8 vendor representatives, and 1 dosimetrist &mdash; and worked for five years until the report was published in January 2018.<\/p>\n<p>The result is more than a list of names. TG-263 defines nomenclature construction principles, laterality rules, conventions for target volumes and their dose levels, standardized notation for dosimetric metrics, and a 10-step implementation workflow that allows any department to adopt the standard without interrupting clinical operations.<\/p>\n<p>This guide covers the full content of the report, includes the complete table with all 717 cataloged non-target structures, explains how the principles apply in daily practice, and details the integration with treatment planning systems, artificial intelligence tools, and multicenter research workflows. The goal is to serve as a comprehensive reference for any professional who needs to implement, audit, or expand TG-263 nomenclature in their department.<\/p>\n<h2 id=\"tg263-o-que-e\">What is TG-263<\/h2>\n<p>The AAPM (American Association of Physicists in Medicine) Task Group 263 was born from the realization that radiation therapy needed a shared technical vocabulary for naming anatomical structures in treatment planning systems. Before this standard, each institution developed its own conventions &mdash; when it developed any at all. The result was a fragmentation that hindered any activity dependent on consistent data across patients, equipment, or centers.<\/p>\n<p>The group was formally constituted in 2012 with members nominated by both the AAPM and ASTRO (American Society for Radiation Oncology). The final composition included 39 AAPM members and 41 ASTRO members, with overlap between the two societies, totaling 57 unique participants. The diversity of the group was intentional: the presence of physicists, physicians, dosimetrists, and vendor representatives ensured that the standard would be viable from both clinical and technological standpoints.<\/p>\n<p>The report was published in January 2018 as AAPM Report No. 263, accompanied by a peer-reviewed publication in Medical Physics (the 2018 S0360 article). The main document defines the principles; the supplemental material, available on the <a href=\"https:\/\/www.aapm.org\/pubs\/reports\/rpt_263_supplemental\/\" target=\"_blank\" rel=\"noopener\">AAPM website<\/a>, contains the complete spreadsheet with all cataloged structures.<\/p>\n<h3>Spreadsheet structure<\/h3>\n<p>The core of TG-263 is a spreadsheet organized into 9 columns that classify each structure systematically. This organization is not arbitrary &mdash; each column serves a specific purpose in the clinical and informatic use chain:<\/p>\n<p><strong>Target Type<\/strong> distinguishes whether the structure is anatomic, a target volume (GTV, CTV, PTV), a PRV, or a derived planning structure. <strong>Major Category<\/strong> groups by broad anatomic system &mdash; bone, nerve, organ, vessel, lymph node. <strong>Minor Category<\/strong> refines this grouping with more specific subcategories. <strong>Anatomic Group<\/strong> indicates the body region: head and neck, thorax, abdomen, pelvis, body, limb.<\/p>\n<p><strong>N Characters<\/strong> records the length of the standardized name, a critical piece of information because TG-263 recommends a maximum of 16 characters to ensure compatibility with legacy systems and interface fields. <strong>TG263-Primary Name<\/strong> is the principal name to be used in the treatment planning system &mdash; for example, <span class=\"tg263-code\">Parotid_L<\/span> for the left parotid. <strong>TG-263-Reverse Order Name<\/strong> provides a reversed version (<span class=\"tg263-code\">L_Parotid<\/span>) to facilitate search and sorting in long lists.<\/p>\n<p><strong>Description<\/strong> provides the full anatomical name without abbreviations. <strong>FMAID<\/strong> maps the structure to the Foundational Model of Anatomy, an anatomical ontology maintained by the University of Washington that enables interoperability with SNOMED CT, DICOM, and other health informatics standards.<\/p>\n<figure><img decoding=\"async\" data-src=\"https:\/\/rtmedical.com.br\/wp-content\/uploads\/2026\/04\/tg263_rpt__p12_0.png\" alt=\"Foundational Model of Anatomy (FMA) ontology applied to lung volumes - TG-263\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" class=\"lazyload\" style=\"--smush-placeholder-width: 1082px; --smush-placeholder-aspect-ratio: 1082\/914;\"><figcaption>FMA ontology applied to lung volumes, illustrating the anatomical concept hierarchy that TG-263 references via FMAID. Source: AAPM TG-263 Report.<\/figcaption><\/figure>\n<h3>Primary Name versus Reverse Order Name<\/h3>\n<p>The distinction between these two fields is one of the most important concepts in TG-263 and is frequently misunderstood. The Primary Name follows the <span class=\"tg263-code\">Structure_Laterality<\/span> pattern &mdash; for example, <span class=\"tg263-code\">Kidney_L<\/span>, <span class=\"tg263-code\">Femur_R<\/span>, <span class=\"tg263-code\">CN_VII_L<\/span>. This format facilitates human reading and follows the natural convention of naming the structure first and then qualifying it.<\/p>\n<p>The Reverse Order Name inverts to <span class=\"tg263-code\">Laterality_Structure<\/span> &mdash; <span class=\"tg263-code\">L_Kidney<\/span>, <span class=\"tg263-code\">R_Femur<\/span>, <span class=\"tg263-code\">L_CN_VII<\/span>. This format is useful when the structure list needs to be sorted alphabetically by laterality, grouping all left-sided and all right-sided structures together. Some treatment planning systems and analysis tools benefit from this ordering for rapid review.<\/p>\n<p>TG-263 recommends that the Primary Name be used as the preferred name in the TPS. The Reverse Order Name exists as a documented alternative, not a substitute. Departments adopting the standard should choose one convention and apply it consistently across all operations.<\/p>\n<h3>Scope: 717 non-target structures<\/h3>\n<p>The spreadsheet catalogs 717 non-target structures organized into 7 anatomic groups: Head and Neck (282), Thorax (180), Abdomen (60), Pelvis (109), Body\/Systemic (52), Limb singular (16), and Limbs bilateral (17). This catalog covers virtually every anatomical structure that a radiation therapy department encounters in clinical practice, from cranial bones and nerves to vessels, lymph nodes, abdominal organs, and pelvic structures.<\/p>\n<p>Beyond anatomical structures, TG-263 defines separate conventions for target volumes (GTV, CTV, ITV, PTV, and their variants), planning structures (PRV, auxiliary structures with the <span class=\"tg263-code\">z<\/span> prefix), and dosimetric metrics (DVH). These three domains follow their own principles, detailed in subsequent sections of this guide.<\/p>\n<h2 id=\"tg263-problemas-reais\">Real-world problems caused by lack of standardization<\/h2>\n<p>TG-263 did not arise from a theoretical concern. Before defining any standard, the group conducted a survey across 20 North American institutions to document the actual state of nomenclature in radiation therapy. The findings were revealing.<\/p>\n<p>Of the 20 surveyed institutions, 16 reported having some form of defined nomenclature for at least some disease sites. But &#8220;having nomenclature&#8221; did not mean having consistency. The number of defined structures ranged from 21 to 311 across institutions, and within each one there were variations between professionals, between rooms, and across time periods. None of the 20 covered all anatomical structures needed for all treatment modalities.<\/p>\n<p>The most cited example in the report is the left optic nerve. When collecting the names used across surveyed institutions, the group found 12 variants for a single structure: <span class=\"tg263-code\">Lt Optic Nerve<\/span>, <span class=\"tg263-code\">L_Optic_Nerve<\/span>, <span class=\"tg263-code\">OpticNrv_L<\/span>, <span class=\"tg263-code\">Optic_Nerve_Left<\/span>, among others. Each variant was internally logical to its creator, but incompatible with the rest when data needed to be combined.<\/p>\n<h3>Impact on data mining<\/h3>\n<p>A department that accumulates 10 years of treatment plans holds a valuable repository for research, benchmarking, and quality improvement. But if those plans use inconsistent names for the same structures, any database query becomes an exercise in manual mapping. Extracting &#8220;all mean doses to the spinal cord&#8221; requires first identifying whether the cord was named <span class=\"tg263-code\">SpinalCord<\/span>, <span class=\"tg263-code\">Spinal_Cord<\/span>, <span class=\"tg263-code\">SC<\/span>, <span class=\"tg263-code\">MedulaEspinhal<\/span>, <span class=\"tg263-code\">Cord<\/span>, or any other local variation.<\/p>\n<p>This mapping cost is not trivial. In multicenter studies with thousands of patients, the nomenclature harmonization step can consume weeks of work and still contain errors. TG-263 eliminates this problem at its source: if all centers use <span class=\"tg263-code\">SpinalCord<\/span>, the database query returns complete results without manual intervention.<\/p>\n<h3>Impact on auto-segmentation and AI<\/h3>\n<p>Deep learning models for auto-segmentation require training data labeled consistently. A model trained on contours labeled <span class=\"tg263-code\">Parotid_L<\/span> cannot automatically use data labeled <span class=\"tg263-code\">Lt_Parotid_Gland<\/span> &mdash; the mapping must be done manually for each variant, and any error in that mapping contaminates the training.<\/p>\n<p>When a department adopts TG-263 nomenclature, its data becomes immediately compatible with models trained at other departments following the same standard. This accelerates the adoption of auto-segmentation, improves training quality by enabling larger datasets, and makes cross-institutional validation feasible.<\/p>\n<h3>Impact on QA automation<\/h3>\n<p>Automated quality assurance protocols depend on predictable names. A script that verifies whether the maximum dose to the lens does not exceed the institutional limit needs to know exactly how the lens is named. If the name varies between <span class=\"tg263-code\">Lens_L<\/span>, <span class=\"tg263-code\">L_Lens<\/span>, <span class=\"tg263-code\">Left_Lens<\/span>, and <span class=\"tg263-code\">Cristalino_E<\/span>, the script needs a synonym table that grows with every new variant encountered &mdash; or, worse, fails silently when it encounters an uncataloged name.<\/p>\n<p>TG-263 allows QA tools to be written once and work in any compliant department. The predictability of names is the foundation for reliable automation.<\/p>\n<h3>Impact on multicenter studies and clinical trials<\/h3>\n<p>Radiation therapy clinical trials that collect dosimetric data from multiple institutions face the nomenclature problem at scale. The RTOG (now NRG Oncology) published naming guidelines for specific studies, but without a universal standard adopted by the community, each new trial repeated the same cycle of definition, communication, and verification. TG-263 provides a permanent foundation that reduces this overhead for any future trial.<\/p>\n<h2 id=\"tg263-rotina-clinica\">How to apply TG-263 in clinical practice<\/h2>\n<p>TG-263 defines two sets of principles: 15 for non-target structures (organs at risk and anatomical structures) and 10 for target volumes. It also standardizes dosimetric metric notation. Each set was designed to solve specific problems in clinical practice.<\/p>\n<h3>Principles for non-target structures<\/h3>\n<p><strong>16-character limit.<\/strong> The standardized name must not exceed 16 characters. This limit is not arbitrary &mdash; it reflects real interface field constraints in both legacy and contemporary treatment planning systems. Longer names are truncated by some TPS, generating ambiguity. The limit enforces conciseness and prevents the proliferation of long descriptive names that no one types identically twice.<\/p>\n<p><strong>Case-insensitive uniqueness.<\/strong> Each name must be unique regardless of uppercase and lowercase. <span class=\"tg263-code\">Brainstem<\/span> and <span class=\"tg263-code\">brainstem<\/span> cannot coexist as distinct structures. This rule prevents errors in systems that ignore case during search or sorting.<\/p>\n<p><strong>No spaces, underscore as separator.<\/strong> Spaces are prohibited in TG-263 names. The standard separator is the underscore (<span class=\"tg263-code\">_<\/span>). Thus, <span class=\"tg263-code\">Optic_Nerve_L<\/span> and not <span class=\"tg263-code\">Optic Nerve L<\/span>. This convention avoids problems with parsers, scripts, and interfaces that treat spaces as field delimiters.<\/p>\n<p><strong>Laterality suffixes: <span class=\"tg263-code\">_L<\/span>, <span class=\"tg263-code\">_R<\/span>, <span class=\"tg263-code\">_A<\/span>, <span class=\"tg263-code\">_P<\/span>.<\/strong> Lateralized structures receive the corresponding suffix at the end of the name. The standard uses single letters for left (<span class=\"tg263-code\">_L<\/span>), right (<span class=\"tg263-code\">_R<\/span>), anterior (<span class=\"tg263-code\">_A<\/span>), and posterior (<span class=\"tg263-code\">_P<\/span>). Bilateral structures without defined laterality use the plural form &mdash; for example, <span class=\"tg263-code\">Kidneys<\/span> for both kidneys, <span class=\"tg263-code\">Kidney_L<\/span> and <span class=\"tg263-code\">Kidney_R<\/span> for each individually.<\/p>\n<p><strong>Category root prefixes.<\/strong> Structures from specific categories use standardized prefixes that facilitate grouping and search:<\/p>\n<p><span class=\"tg263-code\">A_<\/span> for arteries (<span class=\"tg263-code\">A_Carotid_L<\/span>), <span class=\"tg263-code\">V_<\/span> for veins (<span class=\"tg263-code\">V_Jugular_R<\/span>), <span class=\"tg263-code\">LN_<\/span> for lymph nodes (<span class=\"tg263-code\">LN_Ax_L1_L<\/span>), <span class=\"tg263-code\">CN_<\/span> for cranial nerves (<span class=\"tg263-code\">CN_VII_L<\/span>), <span class=\"tg263-code\">Bone_<\/span> for bones (<span class=\"tg263-code\">Bone_Mandible<\/span>), <span class=\"tg263-code\">Musc_<\/span> for muscles (<span class=\"tg263-code\">Musc_Masseter_L<\/span>). These prefixes ensure that all arteries are grouped together in the list, all lymph nodes together, and so on.<\/p>\n<p><strong>PRV structures.<\/strong> Planning Risk Volumes (PRV) follow the convention <span class=\"tg263-code\">Structure_PRV<\/span> for a generic margin or <span class=\"tg263-code\">Structure_PRVxx<\/span> where <span class=\"tg263-code\">xx<\/span> indicates the margin in millimeters. Examples: <span class=\"tg263-code\">Brainstem_PRV<\/span> for a brainstem PRV with an unspecified margin, <span class=\"tg263-code\">SpinalCord_PRV05<\/span> for a spinal cord PRV with a 5 mm expansion. This convention allows any professional to immediately identify the base structure and the applied margin without consulting external documentation.<\/p>\n<p><strong>Partial structures: the tilde (<span class=\"tg263-code\">~<\/span>).<\/strong> When only part of a structure is delineated, TG-263 uses the tilde as a suffix: <span class=\"tg263-code\">Brain~<\/span> for partial brain, <span class=\"tg263-code\">Lung~_L<\/span> for partial left lung. This situation is common in treatments where the acquisition or treatment field does not cover the entire structure &mdash; the tilde explicitly signals that coverage is incomplete, preventing DVH metrics from being interpreted as representative of the whole organ.<\/p>\n<p><strong>Planning structures: the <span class=\"tg263-code\">z<\/span> prefix.<\/strong> Structures created solely for plan optimization &mdash; rings, subtraction structures, dose auxiliaries &mdash; receive the <span class=\"tg263-code\">z<\/span> prefix so they appear at the end of the alphabetical list and do not mix with real anatomical structures. Examples: <span class=\"tg263-code\">zPTVopt<\/span>, <span class=\"tg263-code\">zRing<\/span>, <span class=\"tg263-code\">zBolus<\/span>. The convention is simple and effective: when a physicist scrolls through the structure list, everything starting with <span class=\"tg263-code\">z<\/span> is a planning auxiliary and can be filtered or ignored depending on the context.<\/p>\n<div class=\"tg263-callout warning\">\n<strong>Note on the DICOM limit:<\/strong> The DICOM standard allows up to 64 characters in the ROI Name field of the RT Structure Set. TG-263 recommends 16 characters as a practical limit but does not prohibit longer names. The 16-character recommendation ensures compatibility with TPS interfaces that truncate long names and with database fields sized for the historical standard. In practice, respecting the 16-character limit avoids virtually all truncation and cross-system compatibility issues.\n<\/div>\n<h3>Principles for target volumes<\/h3>\n<figure><img decoding=\"async\" data-src=\"https:\/\/rtmedical.com.br\/wp-content\/uploads\/2026\/04\/tg263_rpt__p29_0.jpeg\" alt=\"Enhanced target definition concept with attributes and associated structures\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" class=\"lazyload\" style=\"--smush-placeholder-width: 991px; --smush-placeholder-aspect-ratio: 991\/620;\"><figcaption>Enhanced target definition concept: each volume carries attributes for type, modality, dose, and motion status. Source: AAPM TG-263 Report.<\/figcaption><\/figure>\n<p>Target volume nomenclature follows 10 principles constructed to reflect the clinical hierarchy between gross tumor volume, clinical target volume, internal margins, and planning target volume.<\/p>\n<p><strong>Volume types.<\/strong> TG-263 defines the following types: <span class=\"tg263-code\">GTV<\/span> (Gross Tumor Volume), <span class=\"tg263-code\">CTV<\/span> (Clinical Target Volume), <span class=\"tg263-code\">ITV<\/span> (Internal Target Volume), <span class=\"tg263-code\">IGTV<\/span> (Internal Gross Target Volume), <span class=\"tg263-code\">ICTV<\/span> (Internal Clinical Target Volume), <span class=\"tg263-code\">PTV<\/span> (Planning Target Volume), and <span class=\"tg263-code\">PTV!<\/span> (evaluation PTV, decoupled from optimization constraints). Each type occupies a precise position in the clinical derivation chain.<\/p>\n<p><strong>Classifiers.<\/strong> Volumes may receive classifiers that indicate the nature of the disease: <span class=\"tg263-code\">n<\/span> for nodal (<span class=\"tg263-code\">GTV_n<\/span>), <span class=\"tg263-code\">p<\/span> for primary (<span class=\"tg263-code\">CTV_p<\/span>), <span class=\"tg263-code\">sb<\/span> for surgical bed (<span class=\"tg263-code\">CTV_sb<\/span>), <span class=\"tg263-code\">par<\/span> for parenchymal. These classifiers combine with the volume type and allow identification of the clinical origin without ambiguity. A plan with <span class=\"tg263-code\">GTV_p<\/span>, <span class=\"tg263-code\">GTV_n<\/span>, <span class=\"tg263-code\">CTV_p<\/span>, and <span class=\"tg263-code\">CTV_n<\/span> communicates in four names the entire coverage strategy for the primary tumor and nodal disease.<\/p>\n<p><strong>Dose levels.<\/strong> When the plan prescribes different doses to distinct volumes, TG-263 allows the level to be indicated in the name: <span class=\"tg263-code\">PTV_High<\/span>, <span class=\"tg263-code\">PTV_Low<\/span>, <span class=\"tg263-code\">PTV_Mid<\/span> for relative levels, or <span class=\"tg263-code\">PTV_5040<\/span> for absolute dose in cGy. This convention is particularly useful in SIB (Simultaneous Integrated Boost) plans, where three or more dose levels coexist and clarity about which PTV receives which prescription is critical for treatment safety.<\/p>\n<p><strong>Target name composition.<\/strong> The elements combine in a predictable pattern: <span class=\"tg263-code\">Type_Classifier_DoseLevel<\/span>. Thus, <span class=\"tg263-code\">PTV_n_High<\/span> unambiguously identifies the nodal planning target volume receiving the highest dose. <span class=\"tg263-code\">CTV_sb_Low<\/span> is the clinical target volume of the surgical bed at the low dose level.

with treatment planning systems and artificial intelligence<\/h2>\n<p>Nomenclature standardization gains operational relevance when it connects with the systems that consume and produce structure names on a daily basis: treatment planning systems (TPS), auto-segmentation tools, and data analysis platforms. TG-263 is not an isolated document &mdash; it is an interoperability layer that enables different links in the chain to communicate without manual mapping.<\/p>\n<figure><img decoding=\"async\" data-src=\"https:\/\/rtmedical.com.br\/wp-content\/uploads\/2023\/05\/Captura-de-Tela-2023-05-25-as-153648.png\" alt=\"Example of auto-segmentation of structures in radiation therapy with TG-263 nomenclature\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" class=\"lazyload\" style=\"--smush-placeholder-width: 278px; --smush-placeholder-aspect-ratio: 278\/283;\"><figcaption>Example of automatic segmentation of anatomical structures in a radiation therapy planning system. Standardized TG-263 nomenclature ensures each structure is consistently identified across systems.<\/figcaption><\/figure>\n<h3>Why standardized nomenclature matters for AI<\/h3>\n<p>Deep learning-based auto-segmentation models depend on three conditions to perform well: large training datasets, consistent labels, and predictable mapping between the model output and the clinical structures in the treatment plan. TG-263 directly addresses the second and third conditions.<\/p>\n<p>When a model is trained on contours labeled <span class=\"tg263-code\">Parotid_L<\/span> across all contributing institutions, the output label can be directly inserted into the plan without a translation step. If each institution uses its own name, the model needs a synonym dictionary that grows with every new dataset incorporated &mdash; and every missing entry in that dictionary is a structure that will not be correctly mapped in the clinic.<\/p>\n<p>The scale of the problem becomes evident in projects like the TCIA (The Cancer Imaging Archive) and AAPM Grand Challenges, where data from dozens of institutions are combined for training and validation. Without standardized nomenclature, the harmonization step consumes more time than model training itself. With TG-263 adopted as the labeling convention, data arrives ready for use.<\/p>\n<h3>Tools that support TG-263 nomenclature<\/h3>\n<p>The radiation therapy ecosystem already offers tools that recognize, map, or enforce TG-263 nomenclature. The list below describes the main ones in an educational and neutral tone, without ranking.<\/p>\n<p><strong>AutoSeg (RT Medical Systems)<\/strong> is an auto-segmentation platform that produces contours with TG-263 names as its default output. Integration with RTConnect allows generated contours to flow directly to the TPS with compliant nomenclature, eliminating the manual renaming step. The complete pipeline &mdash; image reception, segmentation, naming, and delivery &mdash; respects the standard end to end.<\/p>\n<p><strong><a href=\"https:\/\/limbus.ai\/\" target=\"_blank\" rel=\"noopener\">Limbus Contour<\/a><\/strong> combines deep learning with atlas-based approaches for auto-contouring. The tool allows configuration of nomenclature templates that map model outputs to TG-263 names, facilitating integration with workflows that already follow the standard.<\/p>\n<p><strong><a href=\"https:\/\/www.mvision.ai\/\" target=\"_blank\" rel=\"noopener\">MVision AI<\/a><\/strong> operates as a cloud-based auto-contouring service, receiving images via DICOM and returning segmented structure sets. The system offers mapping of output names to TG-263 conventions, useful for departments that adopt the standard and receive contours from different providers.<\/p>\n<p><strong><a href=\"https:\/\/www.radformation.com\/autocontour\" target=\"_blank\" rel=\"noopener\">Radformation AutoContour<\/a><\/strong> uses a combination of atlas and deep learning methods for automatic segmentation. The platform supports structure name customization, allowing departments to configure output to follow the TG-263 convention in their institutional template.<\/p>\n<p><strong><a href=\"https:\/\/www.mimsoftware.com\/\" target=\"_blank\" rel=\"noopener\">MIM Software<\/a><\/strong> offers contouring workflows with customizable structure templates. The ability to define templates with TG-263 names and apply them to new cases facilitates standard adoption in departments that process high patient volumes.<\/p>\n<p><strong><a href=\"https:\/\/www.varian.com\/products\/adaptive-therapy\/treatment-planning\/eclipse\" target=\"_blank\" rel=\"noopener\">Varian Eclipse<\/a><\/strong> includes, starting from ARIA 13.x, a Structure Dictionary that associates TG-263 names with FMAIDs and recognized synonyms. When the physicist creates a new structure, the system suggests the standard name and allows synonym search. This feature lowers the adoption barrier because the professional does not need to memorize the entire catalog &mdash; the system provides guidance during delineation.<\/p>\n<p><strong><a href=\"https:\/\/www.elekta.com\/products\/radiation-therapy\/treatment-planning\/monaco\/\" target=\"_blank\" rel=\"noopener\">Elekta Monaco<\/a><\/strong> supports structure set management and templates that can be configured with TG-263 names. The template tool allows the department to predefine expected structures for each treatment site, enforcing nomenclature from the plan creation stage.<\/p>\n<p><strong><a href=\"https:\/\/www.raysearchlabs.com\/raystation\/\" target=\"_blank\" rel=\"noopener\">RaySearch RayStation<\/a><\/strong> offers scripting capabilities via IronPython and C# that allow building nomenclature validators. A script can check, upon saving the plan, whether all structure names adhere to the TG-263 standard and alert the user if deviations are found. This approach transforms nomenclature from a recommendation into an operational rule.<\/p>\n<h3>Impact on Big Data and multicenter research<\/h3>\n<p>The accumulated value of standardization becomes most apparent at scale. When dozens or hundreds of institutions feed a centralized repository with dosimetric and contour data &mdash; as occurs in Learning Health Systems, outcomes registries, and toxicity prediction projects &mdash; consistent nomenclature is a prerequisite for the data to be usable without intensive manual curation.<\/p>\n<p>Projects that analyze correlations between organ-at-risk dose and clinical outcomes (NTCP models, for example) need to aggregate DVHs from thousands of patients. If each institution names the esophagus differently, the analysis pipeline requires an entity resolution step that is labor-intensive, error-prone, and difficult to audit. TG-263 eliminates this step by defining <span class=\"tg263-code\">Esophagus<\/span> as the canonical, universally recognized name.<\/p>\n<p>The same principle applies to segmentation competitions such as the AAPM Grand Challenges and public repositories like the TCIA. Adoption of TG-263 as the labeling convention in these environments is already underway and is expected to become a formal requirement in future publications. Departments that adopt the standard now position their data to participate in these initiatives without retroactive rework.<\/p>\n<h2 id=\"tg263-implementacao\">Implementation workflow in 10 steps<\/h2>\n<p>Section 13 of the TG-263 report defines a 10-step implementation workflow designed to be applicable to any radiation therapy department, regardless of size or operational maturity. The workflow does not require halting operations &mdash; it is an incremental process that can be executed in parallel with clinical routine.<\/p>\n<p><strong>Step 1: Identify common treatment sites and involved staff.<\/strong> The starting point is mapping which disease sites the department treats most frequently and which professionals participate in delineation, planning, and review for each site. This mapping defines the initial scope of adoption and avoids the mistake of trying to standardize everything at once.<\/p>\n<p><strong>Step 2: Document current naming conventions.<\/strong> Before changing any name, the department needs to document what it already uses. This step reveals the true extent of inconsistency &mdash; it is common for teams to discover variations they did not know existed. Listing the names currently in use for the most frequent structures creates the comparison baseline for the TG-263 standard.<\/p>\n<p><strong>Step 3: Download the complete TG-263 list.<\/strong> The supplemental material from the report, available on the <a href=\"https:\/\/www.aapm.org\/pubs\/reports\/rpt_263_supplemental\/\" target=\"_blank\" rel=\"noopener\">AAPM website<\/a>, contains the spreadsheet with all 717 structures and all 9 columns. This spreadsheet is the reference document for the entire process.<\/p>\n<p><strong>Step 4: Save and create a working copy.<\/strong> The department should keep an intact copy of the original spreadsheet and work from a separate version. The working copy will be customized to the department&#8217;s reality; the original serves as an immutable reference for future consultation and for new professionals who need to understand the standard.<\/p>\n<p><strong>Step 5: Remove structures the department does not use.<\/strong> The complete spreadsheet contains 717 structures, but no department uses all of them. A center specializing in head and neck may start by removing pelvis and abdomen structures that are not part of its practice. This pruning reduces the catalog to a manageable size and focuses the team&#8217;s attention on the structures that actually matter.<\/p>\n<p><strong>Step 6: Discuss with disease-site groups and stakeholders.<\/strong> Each structure retained in the list should be validated by the professionals who use it. Physicians need to agree that the standard names are clinically appropriate. Physicists need to confirm that the names are compatible with existing scripts and tools. Dosimetrists need to verify that the names are practical in the daily delineation workflow.<\/p>\n<p><strong>Step 7: Identify templates and documents that need updating.<\/strong> Nomenclature does not live only in the TPS. Institutional protocols, QA checklists, prescription forms, automation scripts, and dosimetry reports may contain structure names. All need to be reviewed to reflect the adopted standard.<\/p>\n<p><strong>Step 8: Develop a phased rollout plan.<\/strong> The most effective implementation starts with one disease site (typically the most frequent), validates the standard with real cases, and only then expands to other sites. Each phase includes training, monitoring, and adjustment before moving forward. Attempts to implement all sites simultaneously typically result in partial adherence and eventual abandonment.<\/p>\n<p><strong>Step 9: Create TPS templates with standard names.<\/strong> Structure templates in the treatment planning system are the most effective enforcement mechanism. When the physicist or dosimetrist opens a new case and loads the &#8220;head and neck&#8221; template, all structures come pre-named according to TG-263. This eliminates manual typing and dramatically reduces the chance of deviation.<\/p>\n<p><strong>Step 10: Keep the complete list accessible for future reference.<\/strong> New professionals, new modalities, and new disease sites will emerge. The <a href=\"https:\/\/www.aapm.org\/pubs\/reports\/rpt_263_supplemental\/\" target=\"_blank\" rel=\"noopener\">complete spreadsheet (AAPM TG-263 supplemental materials)<\/a> should be available in a known location (network drive, intranet, document management system) so that anyone can consult the standard when they need to add a structure to the local catalog.<\/p>\n<div class=\"tg263-callout\">\n<strong>Pilot study results:<\/strong> TG-263 was tested at 5 institutions prior to publication. The pilot study confirmed that adoption is viable in clinical routine and that the greatest barriers are cultural, not technical. Validation scripts and XML structure templates were the most cited resources for facilitating the transition. Institutions that invested in structured training reported higher adherence than those that simply distributed the spreadsheet.\n<\/div>\n<h2 id=\"tg263-delineamento\">Relationship with target volume delineation<\/h2>\n<p>TG-263 nomenclature does not exist in isolation from the delineation process. On the contrary: it was designed to integrate directly into the contouring workflow, functioning as the identity layer that connects what the physician delineates to what the planning system calculates and what the database stores.<\/p>\n<p>When a radiation oncologist delineates the GTV of a primary oropharyngeal tumor, TG-263 specifies that this structure should be named <span class=\"tg263-code\">GTV_p<\/span>. If there is nodal involvement, lymph nodes delineated as gross disease become <span class=\"tg263-code\">GTV_n<\/span>. The CTV covering the microscopic extension of the primary will be <span class=\"tg263-code\">CTV_p<\/span>, and the nodal one, <span class=\"tg263-code\">CTV_n<\/span>. The PTV generated from the primary CTV at the highest dose level will be <span class=\"tg263-code\">PTV_p_High<\/span> or <span class=\"tg263-code\">PTV_7000<\/span> (if the dose is 70 Gy). Each name carries clinical information that any professional trained in the standard can decode without consulting the chart.<\/p>\n<p>This integration is particularly valuable in head and neck sites, where the number of structures per plan can exceed 40 and the distinction between organs at risk, primary targets, and nodal targets must be unambiguous. A <a href=\"https:\/\/rtmedical.com.br\/en\/nasopharyngeal-target-delineation\/\">nasopharyngeal<\/a> plan with three dose levels, multiple GTVs, and a dense network of organs at risk becomes significantly more readable when the nomenclature follows a predictable standard. The same clarity applies to other head and neck subsites: <a href=\"https:\/\/rtmedical.com.br\/en\/hypopharyngeal-carcinoma-delineation\/\">hypopharyngeal carcinoma<\/a>, <a href=\"https:\/\/rtmedical.com.br\/en\/oral-cavity-radiotherapy\/\">oral cavity<\/a>, <a href=\"https:\/\/rtmedical.com.br\/en\/nasal-cavity-paranasal-sinus-tumors\/\">nasal and paranasal sinus tumors<\/a>, <a href=\"https:\/\/rtmedical.com.br\/en\/salivary-glands-target-delineation\/\">salivary gland tumors<\/a>, and <a href=\"https:\/\/rtmedical.com.br\/en\/thyroid-cancer-delineation-fields\/\">thyroid cancer<\/a> all benefit from unambiguous structure naming when plans involve overlapping organs at risk.<\/p>\n<p>The same principle applies to all anatomic sites. In <a href=\"https:\/\/rtmedical.com.br\/en\/oropharyngeal-carcinoma-target-delineation\/\">oropharyngeal<\/a> delineation, the distinction between mucosal GTV and nodal GTV is immediately visible in the names. In <a href=\"https:\/\/rtmedical.com.br\/en\/larynx-cancer-delineation\/\">larynx<\/a>, where cartilage structures such as <span class=\"tg263-code\">Arytenoid_L<\/span>, <span class=\"tg263-code\">Cricoid<\/span>, and <span class=\"tg263-code\">Thyroid_Cart<\/span> are critical for margin definition, TG-263 names eliminate doubt about which cartilage is being referenced.<\/p>\n<p>In <a href=\"https:\/\/rtmedical.com.br\/en\/early-breast-fields\/\">breast<\/a> treatments, standardized nomenclature facilitates the distinction between <span class=\"tg263-code\">Breast_L<\/span> (whole breast as an organ) and planning structures such as <span class=\"tg263-code\">zBreast_Flash<\/span>. <a href=\"https:\/\/rtmedical.com.br\/en\/lung-cancer-target-delineation\/\">Lung<\/a> plans benefit from the clarity between <span class=\"tg263-code\">Lung_L<\/span>, <span class=\"tg263-code\">Lung~_L<\/span> (partial), and <span class=\"tg263-code\">Lungs<\/span> (bilateral), each name with distinct dosimetric implications. <a href=\"https:\/\/rtmedical.com.br\/en\/regional-nodal-breast-irradiation\/\">Regional nodal breast irradiation<\/a> further demonstrates the value of TG-263, where consistent naming of supraclavicular, axillary, and internal mammary chain structures is essential for reproducible treatment planning.<\/p>\n<p>In the pelvis, <a href=\"https:\/\/rtmedical.com.br\/en\/prostate-ctv-imrt\/\">prostate<\/a> delineation uses <span class=\"tg263-code\">Prostate<\/span>, <span class=\"tg263-code\">SeminalVes<\/span>, <span class=\"tg263-code\">Rectum<\/span>, <span class=\"tg263-code\">Bladder<\/span>, and <span class=\"tg263-code\">Femur_L<\/span>\/<span class=\"tg263-code\">Femur_R<\/span> as standard organs at risk. For <a href=\"https:\/\/rtmedical.com.br\/en\/rectal-cancer-target-delineation\/\">rectal cancer<\/a>, nodal level nomenclature follows the TG-263 <span class=\"tg263-code\">LN_<\/span> convention, making it easy to identify which lymph node chains are included in the CTV. <a href=\"https:\/\/rtmedical.com.br\/en\/bladder-cancer-delineation\/\">Bladder<\/a> and <a href=\"https:\/\/rtmedical.com.br\/en\/definitive-gynecologic-imrt\/\">gynecologic<\/a> delineation follow the same logic. Additional pelvic sites such as <a href=\"https:\/\/rtmedical.com.br\/en\/anal-cancer-delineation-fields\/\">anal cancer<\/a>, <a href=\"https:\/\/rtmedical.com.br\/en\/postoperative-gynecologic-rt\/\">postoperative gynecologic radiotherapy<\/a>, <a href=\"https:\/\/rtmedical.com.br\/en\/vulvar-cancer-imrt\/\">vulvar cancer<\/a>, and <a href=\"https:\/\/rtmedical.com.br\/en\/testicular-seminoma-planning\/\">testicular seminoma<\/a> equally rely on consistent naming for pelvic organs at risk and nodal chains.<\/p>\n<p>In scenarios such as <a href=\"https:\/\/rtmedical.com.br\/en\/brain-metastases-wbrt-srs\/\">brain metastases treated with SRS<\/a>, target volume nomenclature with number identification (<span class=\"tg263-code\">GTV_1<\/span>, <span class=\"tg263-code\">GTV_2<\/span>, <span class=\"tg263-code\">PTV_1<\/span>) becomes critical for traceability. TG-263 allows this numbering within the name composition framework. For intracranial lesions, whether <a href=\"https:\/\/rtmedical.com.br\/en\/benign-cns-tumors-delineation\/\">benign CNS tumors<\/a> such as meningiomas and vestibular schwannomas or <a href=\"https:\/\/rtmedical.com.br\/en\/malignant-cns-delineation\/\">malignant CNS tumors<\/a> such as high-grade gliomas, standardized naming of critical structures like <span class=\"tg263-code\">Brainstem<\/span>, <span class=\"tg263-code\">Hippocampus_L<\/span>, and <span class=\"tg263-code\">OpticChiasm<\/span> ensures reliable plan comparison and outcomes analysis.<\/p>\n<p>The connection between nomenclature and delineation extends to special techniques as well. In <a href=\"https:\/\/rtmedical.com.br\/en\/image-guided-brachytherapy-planning\/\">image-guided brachytherapy<\/a>, structures such as <span class=\"tg263-code\">Applicator<\/span>, <span class=\"tg263-code\">Tandem<\/span>, and pelvic organs at risk follow the same standard. For <a href=\"https:\/\/rtmedical.com.br\/en\/esophageal-cancer-delineation\/\">esophageal cancer<\/a>, <a href=\"https:\/\/rtmedical.com.br\/en\/lymphoma-target-delineation\/\">lymphoma<\/a>, and <a href=\"https:\/\/rtmedical.com.br\/en\/soft-tissue-sarcoma\/\">soft tissue sarcoma<\/a>, TG-263 provides standard names for the site-specific anatomical structures. In abdominal sites, <a href=\"https:\/\/rtmedical.com.br\/en\/gastric-cancer-target-delineation\/\">gastric cancer<\/a>, <a href=\"https:\/\/rtmedical.com.br\/en\/pancreatic-cancer-delineation\/\">pancreatic cancer<\/a>, and <a href=\"https:\/\/rtmedical.com.br\/en\/hepatocellular-target-delineation\/\">hepatocellular carcinoma<\/a> delineation all benefit from consistent naming of structures such as <span class=\"tg263-code\">Stomach<\/span>, <span class=\"tg263-code\">Duodenum<\/span>, <span class=\"tg263-code\">Liver<\/span>, and <span class=\"tg263-code\">Kidney_L<\/span>\/<span class=\"tg263-code\">Kidney_R<\/span>, enabling automated constraint checking and cross-institutional dose comparison.<\/p>\n<p>For a comprehensive overview of how target volume delineation integrates into the radiation therapy workflow, see our <a href=\"https:\/\/rtmedical.com.br\/en\/target-volume-delineation-field-setup-2\/\">complete target volume delineation guide<\/a>, which covers principles, techniques, and recommendations by anatomic site.<\/p>\n<h2 id=\"tg263-futuro\">The future of standardization in radiation therapy<\/h2>\n<p>TG-263 represents the state of the art in structure nomenclature for radiation therapy, but the field continues to evolve. Several developments underway promise to expand the reach and depth of standardization.<\/p>\n<p><strong>Integration with DICOM RT Structure Set.<\/strong> The DICOM standard already supports the concept of a Structure Set, but adoption of TG-263 nomenclature as a controlled vocabulary within DICOM is under discussion. Supplement 196, proposed by DICOM Working Group 7, defines a mechanism for including structure templates directly in the DICOM standard, enabling systems to interoperate not only on data format but also on the semantics of names. When this supplement is widely implemented, the name <span class=\"tg263-code\">Parotid_L<\/span> in a DICOM file will be not just a label, but a semantic identifier linked to an ontology.<\/p>\n<p><strong>HL7 FHIR and medical record interoperability.<\/strong> The HL7 FHIR standard, increasingly adopted for clinical information exchange, offers resources for coding procedures and anatomical findings. The bridge between TG-263 (radiation therapy nomenclature) and FHIR (health interoperability) runs through the mapping of FMAIDs and SNOMED CT codes. This mapping allows radiation therapy data to be integrated into the electronic health record with preserved semantics, enabling queries such as &#8220;which patients received dose > 50 Gy to the left parotid&#8221; directly in the hospital information system.<\/p>\n<p><strong>AI model registries.<\/strong> As auto-segmentation models proliferate, the need arises for registries that document the training nomenclature of each model. If a model was trained with TG-263 labels, any department that uses the standard can adopt it without mapping. If it was trained with proprietary labels, the mapping needs to be documented and validated. The trend is for model registries to include the TG-263 mapping table as mandatory metadata.<\/p>\n<p><strong>Multilingual translation tables.<\/strong> TG-263 was published in English, but departments in non-English-speaking countries need mapping between TG-263 names and local names. Translation tables associating, for example, <span class=\"tg263-code\">Brainstem<\/span> with &#8220;tronco encefalico&#8221; and <span class=\"tg263-code\">SpinalCord<\/span> with &#8220;medula espinhal&#8221; are already in development in several countries. The expectation is that the AAPM or an international working group will publish official correspondence tables that preserve the TG-263 name as the canonical identifier and offer translations as interface aliases.<\/p>\n<p><strong>Task group succession.<\/strong> The original TG-263 was published in 2018 and covers anatomical structures known up to that date. New treatment techniques, new imaging modalities, and new delineation approaches will continue to demand additions to the catalog. Maintaining the standard will require a successor group &mdash; whether linked to the AAPM, ASTRO, or a joint entity &mdash; that periodically reviews the spreadsheet, incorporates new structures, and publishes updated versions. The governance model of this group will determine whether TG-263 remains a living standard or freezes at the 2018 version.<\/p>\n<h2 id=\"tg263-conclusao\">Conclusion<\/h2>\n<p>TG-263 transformed structure nomenclature in radiation therapy from a matter of personal preference into a documented, tested, and adoptable technical standard. The 717 cataloged structures, the 15 principles for organs at risk, the 10 principles for target volumes, and the standardized DVH notation form a complete toolkit for any department that wants to operate with consistency.<\/p>\n<p>The clinical impact is direct. Faster plan review. Usable historical data. Reliable QA automation. Compatibility with auto-segmentation models. Participation in multicenter studies without rework. Easier training of new professionals. None of these benefits depends on sophisticated technology &mdash; it depends on naming discipline.<\/p>\n<p>Implementation does not need to be a months-long project. The report&#8217;s own 10-step workflow shows that starting with one disease site, creating TPS templates, and training the team already produces tangible results in the first week. Expansion to other sites happens naturally as the team internalizes the logic of the standard.<\/p>\n<p>If your department has not yet adopted TG-263, the best time to start is now. Download the spreadsheet, identify the structures for your most frequent treatment site, and create the first standardized template. RT Medical Systems offers tools such as AutoSeg and RTConnect that integrate TG-263 nomenclature directly into the clinical workflow &mdash; from automatic segmentation to contour delivery in the TPS, with compliant names from the start.
