[Insight-users] QuaternionRigidTransform

Hi All,

I have a question about choosing a transform type for my CT-MR image
registration. I have got the voxel size information of the sample datasets
(from DICOM header), do I need to use similarity transform, or only rescale
them to the same voxel size before registration to use rigid transform.

What is the difference between QuaternionRigidTransform and
Similarity3DTransform, I think QuaternionRigidTransform should also be
able to address homogeneous scaling problem. BTW,  Is it necessary to use
affine transform for multimodal registration?

Thanks in advance.

Yan
