[Insight-users] reading Dicom Volume

[shoosh moosh]

Hi Ivan and Mathieu,
Thank you very much for replying.. 
Mathieu, I checked the ITK documentation too, and I didn't find anything where this very particular case is supported and described. Are you talking about a method to read a sub-volume from a larger Dicom volume put together from a bunch of series? If so, could you tell me exactly where this case is handled?
Ivan, your method of selecting certain slices ONLY, is kind of my aim, but I'm also trying to select certain regions from each selected slice to put together a subvolume that doesn't neccessarily have to be of the same width and height of the original slices. Any ideas?
