I really like to read this. If I misunderstood your sentence about a DVD
distribution please forgive me. In a way Jaime is right and not. In Germany a
lot of radiologists are giving away the data together with an application to
view the data to their patients. They ask their patients if they will have it,
you must not ask them to can render the data. I had to judge several scans from
my mother's severe osteoporosis. For some reason she relies more on my amateur
opinion than on the practitioners. I have worked for some 15 years as a male
nurse mainly in oncology so I have the one or other experience with CT data but
I'm far away from being an expert.

Best regards,
Michael
