Abstract
An abnormal pattern detecting apparatus comprises an image operating device which generates a soft tissue image signal representing a soft tissue image, a bone image signal representing a bone image, and an original image signal representing an original image from several image signals representing radiation images of an object, which radiation images have been recorded by exposing the object to at least two kinds of radiation having different energy distributions. A prospective abnormal pattern finding device finds prospective abnormal patterns, which appear in the soft tissue, bone, and original images, by processing the corresponding image signals with an abnormal pattern finding filter. A bone pattern finding device finds information about the positions of bone patterns appearing in the radiation image. From information about the positions of the prospective abnormal patterns and the information about the positions of the bone patterns, a judgment device judges whether the prospective abnormal patterns thus found are or are not true abnormal patterns.
