Executive Summary Prominent among a number of new techniques with which to image the colon, computed tomographic (CT) colonography is extremely attractive because it is noninva-sive and also relatively simple for patients to undergo. As the technology evolves, it is important that gastroenterolo-gists not only understand the multiple issues surrounding CT(More)
Virtual colonoscopy (VC) allows a user to virtually navigate within a reconstructed 3D colon model searching for colorectal polyps. Though VC is widely recognized as a highly sensitive and specific test for identifying polyps, one limitation is the reading time, which can take on average 30 minutes per patient. Large amounts of the colon are often devoid of(More)
Human colon has complex structures mostly because of the haustral folds. The folds are thin flat protrusions on the colon wall, which complicate the shape analysis for computer-aided detection (CAD) of colonic polyps. Fold segmentation may help reduce the structural complexity, and the folds can serve as an anatomic reference for computed tomographic(More)
