[vtkusers] DICOM volumes

[Jim Gerlach]

How do you read/display DICOM volumes where the volume is in one DICOM file. 
For instance,  myfile.dcm contains 29 slices, each slice 64x64 (height x 
width).  vtkDICOMImageReader reads the file but only gives me a 
dimensionality of 2 and vtkImageViewer gives me a GetWholeZMax of 0. 

any help is appreciated, JG
