Registration Using Elastix-- Mutual Information based for CT volume to CT volume

There are lots of modules under elastix. Which module should I use for CT volume to
CT volume registration? And where to put the input file names and how to choose the method?

I think the right place for questions about elastix are on their forum. But I see you already posted there and got an answer!

Yes. Thank You.

I also wanted to know , can I use any itk example to do that?

Yes. This example uses MRIs as inputs, but it should require little to no modification to work with CT images.
