Abstract

PURPOSE:To always keep measuring accuracy constant, by irradiating an examinee with a plurality of monochromatic X-ray beams emitted from a monochromatic X-ray output device and measuring the bone-salt amount contained in the bone of the examinee on the basis of the outputs of detectors separately detecting transmitted monochromatic X-rays at every energy. CONSTITUTION:A monochromatic X-ray output device 30 is constituted of the first and second collimators 34, 36 and a diffraction lattice 38. An examinee 16 is scanned in a left and right direction so as to be cut crosswise while irradiated with X-rays of three kinds of energies. X-ray beams transmit through the examinee 16 and are attenuated by small quantity in soft tissue 16b but attenuated by the quantity corresponding to a bone-salt amount in bone tissue 16a and transmitted X-rays are supplied to a detectors 32. The detection values obtained by the detectors 32a-32c are inputted to a measuring control apparatus 22 to operate the bone-salt amount. Since three kinds of X-rays are used, air can be discriminated from two kinds of the tissues in the examinee 16, and the soft tissue 16b and the bone tissue 16a are discriminated to make it possible to operate the attenuation quantity only of the bone tissue 16a and the bone-salt amount can be accurately measured.
