Objective
Registration of mouse brain images is really hard to achieve properly with certain types of images (in particular T1).Indeed, the size of those images is very different from the size of human brain images. The ratio of rotation, translation and scaling in the transformations is going to be very different in both case. Most modules included in Slicer have default parameters set up for human images. The goal of this project is to provide a framework that is adapted to register easily and automatically mouse brain images in Slicer.
Approach, Plan
During the NAMIC project week, I will try to run the different registration modules available in Slicer to figure out some good sets of parameters that allow good mouse brain registrations. This results will be integrated in DWIProcessPipeline, a module for Slicer that will compute a DTI from a DWI image, register a scalar image computed from the DTI to a template and then computes scalar images from the registered DTI.
- Usecase #3 in the BRAINSFit documentation demonstrates mouse brain registration using BRAINSFit.
Progress
Better registration has been achieved with more optimized parameters. These parameter set will be incorporated into DWIProcessPipeline, a Slicer extension that is being developped.
Delivery Mechanism
This work will be delivered to the NAMIC Kit as a
- NITRIC distribution
- Slicer Module
