SHAPE INFLUENCE IN MEDICAL IMAGE SEGMENTATION WITH APPLICATION IN COMPUTER AIDED DIAGNOSIS IN CT COLONOGRAPHY

Computer-aided diagnosis (CAD) is a procedure in medicine that assists radiologists or physicians in the interpretation of medical images. The application of CAD in screening colorectal cancer (CRC) has been studied for more than two decades. CRC is the second most deadly form of cancer in men and women in the United States. Nearly all CRC arises from polyps and is preventable if polyps are removed in their early stage. Recent researches show that radiologists demonstrated higher accuracy in finding polyps with CAD than without CAD. In this dissertation, we review the current status of CAD research in CT Colonography (CTC) and propose a new method to segment and detect polyps in CTC CAD.
