Key Investigators

  • Queen's: Csaba Pinter
  • MGH: Greg Sharp


Objective

The goal is to extend the SlicerRT DICOM RT import module to be able to import beam geometries

Approach, Plan

  • Acquire sample DICOM-RT dataset containing one beam
  • Have a fiducial at each control point (source, isocenter, etc.): the user

can manipulate (move around) these points or we can lock the fiducials to prevent accidental editing

  • Develop a custom module that observes these fiducials (source, isocenter,

etc.) and creates/updates a model based on these fiducial positions

Progress

  • Sample phantom datasets uploaded in SlicerRT repository
  • Beam-related DICOM tags extracted and stored (DicomRtImport DICOM plugin)
  • Created Beam Visualizer module that
    • Computes source position according to the loaded parameters and added as fiducial point
    • Generates geometry model and places it in the right location

Delivery Mechanism

This work will be delivered to the NA-MIC Kit as a Slicer module, as part of the SlicerRT extension
