[Insight-users] about multi-modality 3D registration

[Yixun Liu]

Hi,

I have a 3D MRI and a 3D CT dataset. I want to register them. Their differences are  the rotation, translation and scaling. The metric is definitely  the MI, but which transform will I take? The Affine or the Versor?  If one of the dataset deforms, I also need to non-rigidly register them. Bspline or FEM?


Thank you in advance!

Regards,

Yixun Liu
