*Abstract

Method and apparatus for detecting abnormal regions such as masses and microcalcifications in living tissue depicted in radiographs such as mammograms is presented by digitizing the radiograph to produce a digitized radiograph, and, by computer, identifying, according to predetermined criteria, any suspected abnormal regions; and for each identified suspected abnormal region, extracting multiple topographic layers of the region from the digitized radiograph; and evaluating the extracted multiple topographic layers' abnormal regions to determine whether the region is an abnormal region; and displaying the abnormal regions in a version of the radiograph. Layers are extracted by thresholding the digital radiograph at a particular threshold value for each topographic layer. The threshold value for each other layer is based on the threshold and contrast values in a previous layer. Application1) The detection of abnormal anatomical regions in radiographs, and, more particularly, to the detection of masses and microcalcifications in digital mammograms.
