I see that Ingo has suggested that you make df3-files from
your photos. I was thinking along the lines too.

For this to work, you need to get the different organs to
stand out visually in the grayscale TGA-images. I.e. they
need to be darker or lighter than their surroundings.
I don't know if this is already the case with your photos.

If not you can try to play around with different color
filtering techniques in a good (preferable scriptable)
image editing program. ("The Gimp" is scriptable IIRC.)

It is also necessary to establish a common reference grid
for the object slices in your images.

Another solution could be to get a MRI (or CT) scan of a
mouse and then convert the data into a df3 file for
rendering with POV-Ray.
