I am interested in taking medical data, such as MRI, CAT, etc, and
putting them together in povray to give a realistic view of the data in
3D. This can be done holographically, by multiply recording the slices
(e.g. http://www.voxel.com), but I want to see how good it would be in
povray.

There is a lot of work in detecting surfaces from the data, but all I
want to do is to stack them up and look at the whole thing, using stereo
or animation.

Questions:

1. Are there sample data sets? I have found one or two, but they are in
formats which I can't read. I would prefer tif, for example.

2. Has anyone done this already in povray? I don't want to reinvent the
wheel.

3. The fun bit is choosing the lighting for each slice, in order that
the slices add up to a good 3D image. Any hints on this?
