Medical images "slice" a patient into thousands of consecutive images.

Images will typically be stored on local disk as well as streamed over the 
network to the workstation. They are then loaded in memory. 

It is not unusual to be looking at 2000-3000 images at a time, each 512x512 
matrix with depth of  12-16 bits of data. We will scroll through the images 
while dragging the mouse as the images are flipped onto the screen.

You also want to have 3d visualization built in.

You do not want to reinvent the display image wheel. 
You want to use Opengl. You want to use VTK.

Take a look at a similar project that is very-very-very Mac centric. It has 
done a marvelous job.

It annoys me that it is so mac centric that I must reinvent the entire project 
from scratch to do it right for linux.
