摘要: A bone data measurement method and apparatus, using an X-ray picture film (20) having a of the sample standard matter gradational steps therein, e.g., aluminum step wedge, in which cursory reading pictures is implemented through detection quantity level light that transmits film, determining maximum ICmax transmitting examined region bone, minutely so as to find thickness portion R₁ matter, larger than close ICmax, adjustably changing illuminating for I R1 within predetermined range light. temperature compensation output from detecting unit, i.e., CCD image sensor (23a) carried out by utilizing shielded (23a).
