I had some CT scans taken this year due to medical issues
and found the data could be provided on DVD on request ;)

Images were in DICOM format and ImageMagick didn't like them,
but they contained uncompressed 16 bit pixel data so conversion
was mostly an issue of discarding the header and guessing width.

This is a stack of 91 horizontal slices that were turned into
a 3d pigment simply as a gradient of image_maps. This allows to
render an arbitrary slice or texture an arbitrary shape, which
is endless fun but doesn't provide too impressive images.

So I turned the pigment into a function and rendered it as
volumetric media, using a density color_map to enhance certain
brightness ranges. This last one looks quite promising.
