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.
Approach, Plan
The first goal is to complete the CLP interface between our in-house registration software (plastimatch) and slicer3, and get ideas how the user interface can be implemented. The second goal is to learn how plastimatch can interface to the fiducial and label maps for interactive deformable registration.
In addition, we will investigate how CTest can be used for automated testing.
Progress
Since last year, we have made quite a bit of progress. (1) Plastimatch deformable registration is now available as an open source software under a BSD-style license. (2) The scaffolding code to implement plastimatch as a slicer3 CLP is complete, though not yet working because plastimatch doesn't read nrrd (yet).
