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](https://groups.google.com/forum/#!category-topic/elastix-imageregistration/elastix/YeBaJ_KQhlo)!

Yes. [This example](https://itk.org/ITKExamples/src/Registration/Common/PerformMultiModalityRegistrationWithMutualInformation/Documentation.html) uses MRIs as inputs, but it should require little to no modification to work with CT images.
