Abstract: PURPOSE: To enable an anatomically abnormal region to be automatically detected by specifying a plurality of locations in a digital image having a possibility as an abnormal region through digital image processing of a subject having an anatomically abnormal region, and by deciding an edge gradient to each region and comparing their threshold values. CONSTITUTION: In the case that a position of cluster containing a signal of a microcalcified part is detected, firstly, it is photographed by an X-ray system and a signal extraction processing 300 is carried out after producing a differential image 200 imputting a digital mammogram 100 digitalized by a laser scanner. Next, with a possible location as a microcalcified part which becomes a problem in the differential image specified, the differential image data in the circumferential region of the specified location is processed in a characteristic extraction processing 600. Next, an area vs contrast test 700 and a contrast vs background test 800 are carried out and a cluster is processed in highlighting by carrying out a cluster filter processing 900.
