Virtual colonoscopy developed by the Departments of Radiology, School of Medicine (SOM) and Computer Science, College of Engineering and Applied Sciences (CEAS) of SUNY at Stony Brook. Top left is a navigation of three simulated polyps inside a pipe phantom and top right is a navigation of a suspected abnormality inside the colon of the Visible Male. Others are the comparison of our virtual colonoscopy with conventional optical colonoscopy for a patient study (from middle left to right are a 4mm polyp in virtual colonoscopy and optical colonoscopy, and the location of the polyp in virtual colonoscopy and optical colonoscopy). On the bottom are a 8mm polyp and its location inside the patient's colon.
