Abstract
The important features of virtual colonoscopy (VC) or computed tomography colonography (CTC), which is a computer-graphics-based alternative to conventional optical colonoscopy, are discussed. VC is patient friendly since the patient undergoes less rigorous preparation prior to the procedure and is also a fast, noninvasive, highly accurate, cost-effective method for mass screening of colon polyps. One of the primary advantages of VC over optical colonoscopy is the ability to interactively and freely pan and zoom the virtual camera for close examinations, and further turn it around to view behind folds and sharp bends. VC is poised to become the procedure of choice for mass screening for colon polyps, the precursor of colon cancer.
