| Abstract(in English) | A computer-aided diagnosis(CAD) system on mammograms is being developed for detecting masses and microcalcifications. These detection schemes uses information about pectoral-muscle region on mammograms. However, it became apparent that the extraction results of pectoral-muscle region had a great influence on the detection performance. In this study, therefore, a new method of extracting the pectoral-muscle 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. |
