Abstract: A technique for Computer Aided Detection (CAD) of colonic polyps, in Computed Tomographic (CT) Colonography is presented. Following the segmentation of the colonic wall, normal wall is identified using a fast geometric scheme able to approximate local curvature. The remaining structures are modeled using spin images and then compared to a set of existing polypoid models. Locations with the highest probability of being colonic polyps are labeled as final candidates. Models are computed by an unsupervised learning technique, using a leave one out technique on a study group of 50 datasets. True positive and false positive findings were determined, employing fiber optic colonoscopy as standard of reference. The detection rate for polyps larger than 6 mm was above 85%, with an average false positive detection rate of 2.75 per case. The overall computation time for the method is approximately 6 minutes. Initial results show that Computer Aided Detection is feasible and that our method holds potential for screening purposes.
