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.

A method of detecting abnormal regions in living tissue depicted in a radiograph, the method comprising the steps of: (a) digitizing the radiograph to produce a digitized radiograph; (b) identifying, according to predetermined criteria, suspected abnormal regions in the radiograph; and (c) for each identified suspected abnormal region, (i) extracting multiple topographic layers of the suspected abnormal region from the digitized radiography, the multiple topographic layers being extracted from the same radiograph; and (ii) evaluating the extracted multiple topographic layers of the suspected abnormal region to determine whether the suspected region is an abnormal region.
