Computer-Aided Classification of Anomalies in Anatomical Structures


Available for licensing is a software enabled method for improving the sensitivity and specificity of computer aided detection (CAD) for computed tomography (CT) or magnetic resonance imaging (MRI) colonography. Colonography is an imaging test that identifies polyps and cancers of the colon and may be useful for reducing the incidence, morbidity and mortality of colon cancer in human beings. The invention comprises three main areas of characterization used to substantially reduce the number of CAD false positives: 1) analysis of the neck of a colon polyp can help distinguish true positive from false positive tumor detections 2) characterization of the colon wall thickness in the proximity of the polyp has been found to be determinative in distinguishing polyps, and 3) templates that mimic the shape of different types of polyps (for example, those on folds, sessile polyps, pedunculated polyps etc.) can improve sensitivity and increase specificity.
