Background
Need to add RT support for Slicer. There were some preliminary work in Slicer3 (using Plastimatch) and new efforts (Plastimatch, DCMTK/DCMRT, SparKit).
Key Investigators
- MGH: Greg Sharp
- NA-MIC: Steve Pieper
- Queen's University: Andras Lasso
Objective
- Find a good representation of RT structure sets in Slicer.
Approach, Plan
- Specify requirements for representing structure sets in Slicer
- Decide on the design
- Implement the solution in Slicer4
Progress
- Preliminary discussions
Notes
- Requirements
- Support up to 100 structures
- Support overlapping structures
- Display a name for each structure
- Show/hide each structure
- Manual editing of each structure
- Rigid/deformable transform of the structures
- DICOM-RT export
- Design options
- Store each structure as one labelmap (lots of memory, data loss when converted from contours)
- Store multiple structure in a labelmap as bitfield (limited to 32 structures, complicated editing, data loss when converted from contours)
- Store as model or annotation contours (not the usual representation for segmented structures, models cannot be edited)
