This picture of me was taken in the 1990s when I was developing a medical simulation system for catheterization. In the photo, you can see that I hung catheters on the window panel next to the door of my office.
The simulation system was a new concept and a novel approach in providing physicians with a real-time interactive simulation of vascular catheterization procedures. Its purpose was to enhance training, as well as improve pretreatment planning and the design of medical devices. https://www.nlm.nih.gov/archive/20120612/research/visible/vhp_conf/chui/index.htm
