You have to be careful--not all companies' DICOM
implementations are created equal.

In order to use vtkDICOMImageReader on a stack of
images generated by a Siemens machine in their
Somatom5 format, I first had to rename each slice
file using ezDICOM
http://www.psychology.nottingham.ac.uk/staff/cr1/ezdicom.html
since the Siemens software seems to pick file names
out of the air -- i.e., they're not ordered in any
obvious way.

Souldn't be necessary; you should be able to point
vtkDICOMImageReader to the directory containing the
files and it sucks up all the files for you.

vtkDICOMImageReader vd
   vd SetDirectoryName "C:/Path/To/Your/DICOM/Files/"
