[Insight-users] register two volumes of different types

[Grace Chen]

MessageHi George, 

Thanx for your reply. What makes my program a bit challenging is the fact that I am trying to register two volumes of different types (one is T1 weighted image and the other is diffusion weighted image).  They have different physical dimensions, different number of slices, and the way the data looks is quite different too.  My ITK program used to work for the volumes of the same time, but now I try to run it with two volumes of different types, it gives me segamentation fault.  Do you know why?

Grace

  Grace:

  It does not have any restriction on the dimension of the two image volumes.

    Hi there,  Good day!

    I have two 3D image data I want to register.  The movement in the data is 3D rigid.  So, I use VersorRigid3DTransform.  The two volumes are different types of image data (one is T1 image, and the other is diffusion weighted image), so I use MattesMutualInformationImageToImageMetric. I know ITK can register two volumes of different physical dimension.  But doesn't it also register two volumes that have different number of slices?  My program doesn't work for two volumes of different types, am I missing something?
