Registration of MRI to CT for the Spine



Hi, sorry to bother you all again. I have to registered the T1 to T2 scans just fine using the Brainsfit Module, however with regards of T2 to CT scans I am having a bit of trouble.
I already used “Fudicial Registration” to get initial allignment for the registration, but when I attempt to use non-deformable registration it seems like the scans automatically get cropped. (This occurs in a multitued of the other registration phases as well) and the scans are not as alligned as I want them to be.

I was wondering if there are any resources for spine registration? Or what parameter needs to be changed so at least the entire scan is not cropped to a specific location in the spine.
