# Demonstrates use of a DICOM file.
# You must unzip Abdomen.zip before you run this example.
# Reads in and displays a 3 slice scan of an abdomen.
# The display writes very slowly to the screen.
# This will be improved in an upcoming new release.
# Until then, one useful trick is that if you iconize the graphics window,
# then un-inconize it when drawing is done, the drawing will go much faster.
