[slicer-users] Register T1 MRI image to DTI space

Hi Thomas,

We found that it is very efficient to register the skull-stripped T1 image
(brain only) with the averaged DWI images (slicer2 used to export this as
av_gradient or trace-weighted image). Although it was not evaluated in
detail, this approach seems more robust than the B0 -> T1 as that generally
enlarges the brain a little bit.

hope that helps
András
