Wrong web site. I don't like having to do multiple clicks and download/save the image. I gave up. That's why I like tinypic.com - first click and there it is, immediately viewable, no additional clicks needed.

That is too challenging a project for us to answer in a forum like this. Looks more like what people do for a Ph.D. project. In fact I'm sure some have. Have you checked the literature: http://iris.usc.edu/Vision-Notes/bibliography/contentsmedical.html#Medical%20Applications,%20CAT,%20MRI,%20Ultrasound,%20Heart%20Models,%20Brain%20Models
