I have thinking about and working on an application to render the data from the Visible Human Project for a long time. When I started working on the project I was naive to the huge difficulty this represents. The main difficulty is: How do we get the computer to isolate the various organs for display on the screen. It turns out that this is a problem in computer vision, an area of active research akin to artificial intelligence. There are multiple methods for doing this. I chose the method called, Watershed Segmentation, to accomplish this. I'm using ITK's implementation. I will try to post more on this in time.
