PROBLEM TO BE SOLVED: To provide a medical X-ray measuring apparatus capable of measuring a reference material or a phantom together with a portion to be examined, and also capable of optimizing the posture of the phantom.SOLUTION: A subject 14 is placed on a placement surface 12. An X-ray generator 16 is disposed above the placement surface 12, and an X-ray detector 22 is disposed below the placement surface 12. A three-dimensional X-ray beam 18 is formed by the X-ray generator 16, and a phantom 26 is placed in the three-dimensional beam space together with a portion to be examined. The phantom 26 is supported by a support mechanism 28 and an inclination angle of the phantom 26 is adjustable. The inclination angle is determined so that a central axis in the phantom 26 is directed to the X-ray generation origin. |
