  7. Actors • Archive • Contourer • Geometric Planner • Dosimetric Planner • Dose Displayer

  8. Connectathon 2006 • Timing Week of September 25th, 2006 • Location “undetermined” • Use Cases • Single Contoured/Image Series Retrieval • Structure Set Storage • Geometric Plan Storage • Dosimetric Plan Storage • Dose Storage • Multi Series Image Review • Structure Set Retrieval • Geometric Plan Retrieval • Dosimetric Plan Retrieval • Dose Retrieve • Combined CT Storage

  9. Single Contoured/Image Series Retrieval • Description: In the Single/Contoured Image Series Retrieve transaction, the Archive sends a series of CT-Images to the Contourer, Geometric Planner, or Dosimetric Planner. • Actor: Archive • Role: Transmit CT Series to Contourer, Geometric Planner, or Dosimetric Planner • Actor: Contourer, Geometric Planner, or Dosimetric Planner • Role: Receives and stores CT Series from Archive

  10. Structure Set Storage • Description: In the Structure Set Storage Transaction, the Contourer stores a Structure Set on an Archive to make it available. • Actor: Contourer • Role: Sends Structure Set to Archive • Actor: Archive • Role: Stores Structure Set received from Contourer

  11. Geometric Plan Storage • Description: In the Geometric Plan Storage transaction, the Geometric Planner sends the newly created Geometric Plan to the Archive. • Actor: Geometric Planner • Role: Transmit generated Geometric Plan to the Archive • Actor: Archive • Role: Receives and stores Geometric Plans from the Geometric Planner

  12. Dosimetric Plan Storage • Description: In this transaction, the Dosimetric Planner sends the plan containing the references to the structure set to the Image Archive. • Actor: Dosimetric Planner • Role: Transmit generated plan to Image Archive. • Actor: Archive • Role: Accept and store plan from Dosimetric Planner.

  13. Dose Storage • Description: In the Dose Storage transaction, the Dose planner sends the newly created Dose to the Archive. • Actor: Dosimetric Planner • Role: Transmit generated Dose to the Archive • Actor: Archive • Role: Receives and stores Doses from the Dosimetric Planner

  14. Multi Series Image Review • Description: In the Multi-Series Image Retrieve Transaction, the Archive stores CT Images from multiple series (but a single study) on a Contourer to make these Images available for contouring. • Actor: Archive • Role: Sends CT Images to the Contourer • Actor: Contourer • Role: Stores CT Images received from Archive

  15. Structure Set Retrieval • Description: In the Structure Set Retrieval Transaction, the Archiver stores a Structure Set on a Contourer, Geometric Planner, Dosimetric Planner, or Dose Displayer. • Actor: Archive • Role: Sends Structure Set to Contourer, Geometric Planner, Dosimetric Planner, or Dose Displayer • Actor: Contourer, Geometric Planner, Dosimetric Planner, or Dose Displayer • Role: Stores Structure Set received from Archive

  16. Geometric Plan Retrieval • Description: In the Geometric Plan Retrieve Transaction, the requested Geometric Plan is transferred from the Archive to the Dosimetric Planner. • Actor: Dosimetric Planner • Role: Receives requested Geometric Plan from the Archive • Actor: Archive • Role: Sends requested Geometric Plan instance to the Dosimetric Planner

  17. Dosimetric Plan Retrieval • Description: In this transaction, the dose displayer retrieves the plan containing the references to the structure set to the Image Archive. • Actor: Dose Displayer • Role: Accepts plan from Archive. • Actor: Archive • Role: Transmits plan to Dose Viewer.

  18. Dose Retrieve • Description: In the Dose Retrieve Transaction, the requested Dose is transferred from the Archive to the Dose Displayer. • Actor: Dose Displayer • Role: Receives requested Dose from the Archive • Actor: Archive • Role: Sends requested Dose instance to the Dose Displayer

  19. Combined CT Storage • Description: In the Resampled/Combined CT Series Storage Transaction, the Contourer stores CT Images which have been combined or resampled into a single series on the Archive. • Actor: Contourer • Role: Sends CT Images to the Archive • Actor: Archive • Role: Stores CT Images received from Contourer

  20. Connectathon 2007 • Worklist / Scheduling & GP Worklist • Complete External Beam Definition of RT Plan • Multi-Modality Fusion

  21. GP Worklist Treatment Delivery including • Selecting a Treatment from the Oncology Information System (OIS) • Sending Treatment to Treatment Delivery System • Setup & Position Verification including Imaging and Other Devices • Image Acquisition Including CT • Delivering Treatment • Saving Treatment Record • Updating the OIS IODs Documented in DICOM Draft Supplement 74 : Utilization of Worklist in Radiotherapy Treatment Delivery

  22. RT Plan Profiles • Profiles will be specified in terms of beam delivery types. • Each beam type supports a subset of modifiers. • Conformance will be specified with respect to the beam type profile and supported modiers.

  23. RT Plan Conformance Beam Modifiers Beam Profiles

  24. Multi-Modality Fusion • Affine, Deformable, Global, Local • CT, MR, PET, US, SPECT • Multiple (~30) Volume Datasets • CBCT Support • Contour redefinition vs Contour Pasting

  25. Future Direction • Brachytherapy (LDR & HDR) • Clinical Trials Submissions • 4D : gating, breath hold, adaptive, fluoroscopic monitoring • Plan transfer to treatment delivery device • Enhanced dose exchange • Enhanced worklist : Dose Calculation Scheduling, Planning Scheduling (Simulation, Contouring, Planning) • Multiple-independent delivery devices – Micro MLCs • ION Support
