| 1. A computer-assisted method for detecting surface features in a virtual colonoscopy of a patient's colon, comprising:
providing a three-dimensional construction of a computed tomography colonography surface of the patient's colon;
creating a path along the teniae coli from the proximal ascending colon to the distal descending colon on the colonography
surface; and
forming an indexed computed tomography colonography surface using the created path.
