[Insight-users] Fundamental question about image registration

[Matthias Keil]

Dear all,

me and a colleague came up with a fundamental question about how to 
choose the fixed and moving image for the registration.

My colleague is working with a PET Volume with a pretty bad resolution 
and a CT volume with a small voxel size.

In my case I deal with an Ultrasound volume with 0.1132 mm resolution in 
plane and 2 mm plane thickness and a CT volume with 0.5 mm in each 
direction.

The question is now would you choose the volume with better resolution 
as the fixed image or would you use it to move around?

I tend to use the CT images (better resolution) as moving images.

Is there a rule of thumb or a scientific answer to our problem? Maybe 
even a publication?

Thanks in advance for your help!
Matthias
