    Gastrointestinal (GI) tract examination with computed tomography (CT) is currently performed by slice-based visual inspection despite the volumetric nature of the problem. The entire abdomen may now be continuously scanned within a single breath-hold with spiral CT. The GI tract can be computationally extracted from spiral CT images, the lumen explicitly unraveled onto a plane, and colonoscopy virtually simulated via fly-through display. A semi-automatic approach was developed for fly-through and unraveling in vivo. Automation of this approach was investigated in numerical simulation. The techniques are promising for colon cancer screening.
