Slicer is not able to work with DICOM Files which were
aquired with different slice spacings.
At modern CTs, the slice distance between slices can
change throughout the Series. Slicer cannot handle this
kind of data. (Some of the users copy files so they can
manually produce a constant slice distance, which
works, but doesn't give new information when a model is
built.)
