Objective
We are determining which methods of registration in slicer (and other tools) work best for registration of various types of volumes. Our focus is currently on registering data from structural to DTI space.
Approach, Plan
We're going through each type of registration and registration pipeline in Slicer 3 with a specific image to test which methods give the best results. We are also performing comparisons with FSL's FLIRT and FNIRT tools.
Progress
Some of Slicer 3's registration works ok, but it currently has no good way to register from structural to DTI, and no way to apply a similar transform to a label map from structural space. Currently we must use FSL tools to accomplish this. Luis Ibanez has been helping us with developing tools outside of Slicer that seem to be performing well.
