Hi Ivan and Mathieu,<BR>
Thank you very much for replying.. <BR>
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?<BR>
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?<BR>
