This is being done! We provide exactly what your are speculating about.
Namely physical models produced from CT (or MRI) scans for health care use.
Doctors find these models especially useful for pre surgical planning for
complex bone reconstruction surgeries. Our middle step is the virtualization
of the CT scan into a 3D image and save it as an STL file. Then create the
model. See our web site for some examples.
We also provide standard RP services for the engineering, architectural,
legal and entertainment communities.

Subject: Virtual endoscopy?

Hello list,
I have just recently learned of a "new" technology that allows viewing of CT
scan data three-dimensionally. It is called "virtual endoscopy" and I
suspect that many of you may already know this to be not-so-new, but it is
new to me. It is my understanding that use of this technology/software
allows 3D visualization of CT scan data in a real-time or near real-time
setting. Harvard University as well as several other institutions seem to
be exploring application of this innovation.
My question is this: Aside from the obvious medical advantage of being able
to immediately "see" a 3D image of a trachea, colon, etc., is the data
acquired from such a manipulated scan any more useful for the creation of a
solid model using traditional engineering software, and, or, can it yield
better, faster, more accurate data for creation of SL models?
Opinions and direction to additional information on the subject is welcomed.
