One such paper is "The display of 3-D anatomy with stereolithographic
models" SPIE 1232 MEDICAL IMAGING IV, 1990, Nicholas J. Mankovich,
Andrew M. Cheeseman, and Noel G. Stokert.
This paper discribes work which Nick did in cooperation with 3D Systems
in 1989. I was providing technical support from the 3D Systems side of
the project.

As far as I am aware there were no patents issued for this work.

This was the first anotomical model produced directly from CT data using
3D Systems equipment.

I have continued this work with Dr. Mankovich after leaving 3D Systems
and starting SCICON Technologies in 1990. Our main obstical to
comercialzation has not been technical or patent related, but purly
financial. We have not figured out how to do this type of work
profitably with the current medical reimbursment in the U.S. today.
