DICOM RTSTRUCT, originally developed for radiotherapy planning, has evolved into a versatile standard that serves two crucial purposes in modern healthcare: radiation therapy planning and medical image segmentation. This dual role has made it an indispensable tool for both clinical treatment and research applications, particularly in the era of AI-driven medical image analysis.
DICOM RTSTRUCT's journey from a specialized radiotherapy format to a broader medical imaging standard reflects the evolution of healthcare technology itself. As quoted by the DICOM Standards Committee:
"DICOM® — Digital Imaging and Communications in Medicine — is the international standard for medical images and related information. It defines the formats for medical images that can be exchanged with the data and quality necessary for clinical use."
While its primary role in radiation therapy remains crucial, RTSTRUCT has become equally important in the broader field of medical image analysis, particularly for segmentation tasks in research and clinical trials. This expansion has been driven by the format's robust ability to store and communicate precise anatomical definitions across different systems and platforms.

In radiation therapy, RTSTRUCT serves its traditional role by enabling precise definition of treatment areas and organs at risk. Radiation oncologists use this format to delineate tumor volumes and critical structures, ensuring accurate treatment delivery while minimizing exposure to healthy tissue.
Beyond radiotherapy, RTSTRUCT has become the go-to format for storing and sharing segmentation data in medical imaging research. Modern platforms like Collective Minds Research utilize RTSTRUCT for managing large-scale segmentation projects, where AI algorithms and human experts collaborate to analyze medical images across various modalities.

RTSTRUCT's technical foundation enables precise structure definition while maintaining compatibility across different systems. According to the Imaging Data Commons (IDC) documentation:
"DICOM Radiotherapy Structure Sets (RTSS, or RTSTRUCT) define regions of interest by a set of planar contours. RTSS objects can be identified by the RTSTRUCT value assigned to the Modality attribute."
The format employs a sophisticated approach to storing anatomical structures, supporting both traditional radiotherapy needs and modern research requirements. This includes:

The journey of medical imaging data from acquisition to analysis demands rigorous quality control, whether in clinical radiotherapy or research settings. In radiotherapy, where treatment accuracy directly impacts patient outcomes, RTSTRUCT's standardization ensures precise structure definition and treatment delivery. Similarly, in research applications, this standardization enables consistent data handling across large-scale studies and multi-center trials.
When researchers and clinicians collaborate through platforms like Collective Minds Research, the consistency of structure definitions becomes paramount. RTSTRUCT's standardized format enables teams to speak the same language when it comes to anatomical structures, regardless of their geographical location or the systems they use. This uniformity extends beyond mere definitions – it encompasses the entire chain of data handling, from initial AI-driven segmentation to final expert validation.
