ABSTRACT:
Digital image signals are detected from radiation images of an object constituted of bones and soft tissues, which radiation images have been formed with at least two kinds of radiation having different energy distributions and having passed through the object and in which different images of at least part of the object are embedded. A substraction process is carried out on the digital image signals, and a difference signal representing a soft tissue image and a difference signal representing a bone image are obtained. Different image processing operations are carried out on the difference signal representing the soft tissue image and the difference signal representing the bone image. The difference signals, which have been obtained from the image processing operations, are then added together. A visible radiation image of the object is reproduced from an image signal, which has been obtained from the addition.
