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