Computer-aided classification of anomalies in anatomical structures
First Claim
1. A computer-implemented method for processing a detected anomaly in an anatomical structure, the method comprising:
- in a digital representation comprising a representation of the anomaly, measuring a characteristic of a neck of the anomaly; and
based at least on the characteristic of the anomaly neck, classifying the anomaly.

Abstract
Candidate anomalies in an anatomical structure are processed for classification. For example, false positives can be reduced by techniques related to the anomaly'"'"'s neck, wall thickness associated with the anomaly, template matching performed for the anomaly, or some combination thereof. The various techniques can be combined for use in a classifier, which can determine whether the anomaly is of interest. For example, a computed tomography scan of a colon can be analyzed to determine whether a candidate anomaly is a polyp. The technologies can be applied to a variety of other scenarios involving other anatomical structures.
