  Projects List

  Beams loaded for prostate phantom dataset

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
