Three-dimensional Spiral CT Colonography (originally Brooke Jeffrey and now Chris Beaulieu, Principal Investigator):

Combining rapidly acquired thin-section CT scans of the air filled colon with 3D visualization resulted in a completely new method for assessing the colon for polyps, the precursors to colon cancer. More recently we have been developing computer-aided interpretation methods to aid the radiologist in the difficult task of searching the image data for these lesions.
