A phase-contrast X-ray CT apparatus is provided with an X-ray source (7) for generating an X-ray beam (8), a crystal (9; 21) for generating a diffracted beam (10a) by irradiation with the X-ray beam, an object arranging section provided in the direction of propagation of the diffracted beam so that it is rotatable relative to the diffracted beam, an analyzer crystal (11; 22) for receiving a beam transmitted through the object arranging section to extract only a specified refraction angle component, and a sensor (6) for detecting a beam extracted by the analyzer crystal. <IMAGE> |
