Abstract
Arie E. Kaufman This talk will introduce the 3D virtual colonoscopy (VC), which is a combination of computed tomography (CT) scanning and volume visualization technology. VC is poised to become the procedure of choice in lieu of the conventional optical colonoscopy for mass screening for colon polyps - the precursor of colorectal cancer. The patient abdomen is imaged by a helical CT scanner during a 40-second single-breath-hold. A 3D model of the colon is then reconstructed from the CT scan by automatically segmenting the colon out of the rest of the abdomen and employing an "electronic cleansing" algorithm for computer-based removal of the residual material. The visualization software allows the physician to interactively navigate through the colon using volume rendering. An intuitive user interface with customized tools supports 3D measurements, "virtual biopsy" to inspect suspicious regions and "painting" to help in visualizing 100% of the colon surface. Unlike conventional optical colonoscopy, VC is patient friendly, fast, non-invasive, more accurate, cost-effective procedure for mass screening of colon polyps. The talk further discusses a novel pipeline of computer-aided detection (CAD) of colonic polyps, complementing VC. Our CAD pipeline automatically detects polyps by integrating volume rendering, conformal colon flattening, and clustering, with texture and shape analysis.
