Objective
The goal of this project is to develop a command line module for slicer 3 to resample DT images. This module will be compatible with several ITK 3D transforms (rigid, affine and non-rigid) and implements different diffusion tensor interpolations.
Approach, Plan
Our approach is to build the ITK infrastructure (ITK diffusion tensor interpolators and ITK diffusion tensor transforms) to support this module. Our main purpose at the Project Week is to implement a non-rigid transform for diffusion tensor images.
Progress
The module currently supports:
- Several blockwise diffusion tensor interpolations
- Nearest Neighborhood
- Linear
- BSpline
- Some Transforms
- Rigid3D
- Affine - Finite Strain
- Affine - Preservation of Principal Direction
To implement:
- non-rigid transforms
- better interpolations
