Scope:

WG-07 develops and maintains the radiotherapy objects and related functionality in the DICOM Standard and supports and promotes its adoption by industry and community. Specifically, the following objectives are included:

  • Modernizing and streamlining the DICOM Standard for Radiotherapy by developing modernizations  of Radiotherapy-related IODs
  • Taking care that Imaging is well-integrated into the Radiotherapy Process
  • Ensure, that geometric concepts (frame of reference and related constructs) are well-defined so that radio-therapeutic planning and delivery can rely on precise geometric definitions to ensure safe beam placement
  • Considering and further developing DICOM specifications and making use of those approaches into the Radiotherapy workflow

    Challenges and Opportunities (Environment):

    • Radiation Therapy delivery devices have diverged significantly in recent years from a traditional C-Arm linac delivery geometry. As such, standardizing the geometry and delivery mechanisms of all possible treatment machines is not possible. The emphasis now is on providing a DICOM structure within which multiple designs of machine can store their treatment plan and delivery data while sharing images, structures, doses and treatment progress with others.

    Future Roadmap and Objectives (Committee Direction):

    • Enhancing the RT DOSE object with more detail since this object will be critical for continuation of care.  
    • Provide a common RT PLAN and RT Treatment Record within which any design of external beam machine can store their data- an “RT Alternate Beam Module”.
