Objective
The long term objective is to improve interactive tools for radiation therapy planning. Specifically, we would like to improve the reliability and usability of image registration and segmentation of critical organs.
Approach, Plan
Workshop goals
- Complete the CLP interface between our in-house registration software (plastimatch) and slicer3
- Get ideas how the user interface can be implemented
- Learn how to interface with slicer3 fiducial and label maps for interactive deformable registration
- Learn how CTest can be used for automated testing
Progress
Since last year
- Plastimatch software released under open source software license (BSD-style).
- The scaffolding code to implement plastimatch as a slicer3 CLP is complete, though not yet working because plastimatch doesn't read nrrd (yet).
