[Insight-users] 3D image registration

[Grace Chen]

Hi all,

I post my question a few days ago and didn't get any feedback.  So, I post my question again in the next pargraph hoping someone today will be able to help me with this problelm.  I am a new ITK user, so my question should be trivial for those who use ITK's registration tools.  Please help!! :>  Thanx!!

Subject: [Insight-users] 3D image registration


Hi there,  Good day!   We are using ITK for registering 2D images for our current project.  It's working very nicely for correcting most of the misalignment in our data.  However, we noticed out-of-plant movement in our image data, so we want to extend our project to perform 3D rigid registration.  The data I have is the MR scan for the brain.  The dimension of the image is (256, 256, 8), and the spacing is (0.93mm, 0.93mm, 7mm). 
So, our problem is: since the space between neighbor slices is so distant, can the ITK
registration program perform 3D registration properly on this type of data? ...or do we have to
use some additional VTK/ITK tools to cope with that?   If we can use ITK to register our data, can you recommand the registration component good for our data?   Any help is greatly appreciated!! :>   Have a great day!   Grace
