摘要: Two radiation images of a single object, which comprises soft tissue and bone tissue, are formed respectively with two kinds having different energy distributions, the being to be subjected subtraction processing. The processing is carried out on images, image, in pattern object has been extracted or emphasized, thereby formed. Numerical information concerning density constituent obtained accordance image. A trabecula emphasizing process representing form trabeculae obtained.
