<br>
These links detail a refactor of the image class hierarchy which would<br>
support multi-slice images. Note that this is not yet implemented; I<br>
believe the implementation is part of the ITKv4 activities. This<br>
refactor would solve your issues, because a multi-slice image could<br>
then be treated as a "normal" image and simply registered with the<br>
existing registration framework.<br>
<br>
Cheers, Dan<br>

Maybe I'm wrong, but it looks like that the examples aren't suitable to solve my problems (all registrations seem to be between "similar" images).<br>
