Abstract:
1. An abnormal shadow detecting system comprising a prospective micro calcification point extracting means which extracts prospective micro calcification points in a radiation image of an object on the basis of image data representing the radiation image, and a cluster area setting means which clusters the extracted prospective micro calcification points to set cluster areas, wherein the cluster area setting means: sets a plurality of areas in a radiation image; obtains at least one of fluctuation in size and fluctuation in density of prospective micro calcification points in each of the areas; extracts detected areas from the plurality of areas on the basis of at least one of fluctuation in size and fluctuation in density of the prospective micro calcification points in each of the areas; and sets each interconnected area where a predetermined number of or more extracted detected areas are continuous as a cluster area.
