Objective
We are developing capabilities for Slicer to display and manipulate overlapping structures.
Approach, Plan
An initial approach, used in plastimatch, is to represent structure sets as a vector of unsigned characters, with one bit per structure.
Progress
- Discussions of target data types and capabilities:
- Typically around 100meg for a Head/Neck CT
- Typically no more than 100 structures
- Goal is to provide lossless representation of original data, with conversion from contours to images for editing and warping
- Keep original contours as slicer models (view in slices as slice intersections)
- Provide routines to rasterize contours into label volumes on demand for editing on a per-structure basis
- Create vector image representation for running warp operations (warp all structures with single evaluation of pixel deformation function)
Delivery Mechanism
This work will be delivered to the NA-MIC Kit as a modification of Slicer interals
