Module Description
This is the plastimatch automatic (B-spline) deformable image registration module. It includes a multi-stage, multi-resolution pipeline, as well as multicore and GPU acceleration. Compared to other B-spline methods in 3d slicer, the plastimatch registration method might offer:
- superior accuracy for CT-CT (or CT-CBCT) registration
- faster results for MSE registration
However, to date there have been no rigorous comparisons of the various 3D Slicer registration methods.
Examples of how this module is being used:
- Intra-subject registration for adaptive radiotherapy
- Inter-subject registration for automatic segmentation
