I worked with SGI workstations at UCSD around 2005-2007 where the School of Medicine had some Indigo2, Onyx, and Indys[1]. They ran a custom OpenGL software called Anatomic VisualizeR© that displayed full 3d models of a human body, scanned slice-by-slice [2].

My boss at the time offered me $2000 if I could port it from Irix to Linux, but my C skills weren't that great and I don't think they ever did.
