[Insight-users] Extraction of a oriented subimage

[Luis Ibanez]

Hi Teo,

The ResampleImageFilter is what you can use in order to extract
that sub-image in the desired orientation.

You don't need to apply this twice. Just need to have a careful
selection of the Transform parameters.


    Regards



       Luis
