Description

We have been developing a computer-aided diagnosis (CAD) system for mammagrams. The system detects mammographic masses based on a thresholding technique depending on an automated classification result of mammographic parenchymal patterns. However, it became apparent that the extraction results of pectoral-muscle region had a great influence on the classification categories. In this study, therefore, a new method of extracting the pectoralmuscle region was developed, which divides pectoral-muscle region from mammary region in the mammogram. Pectoral-muscle region was determined on edge-enhanced image obtained by Prewitt filter, by searching a boundary of these two regions. The boundaries in 502 of 513(98%) were extracted correctly by employing 513 images. These results demonstrated that the new algorithm developed may be effective to improve the performance of our CAD system.
