<DIV><FONT face=Arial size=2>Hi,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>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?</FONT></DIV>
