ABSTRACT:
A phase-contrast X-ray CT apparatus is provided with an X-ray source for generating an X-ray beam, a crystal for generating a diffracted beam 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 for receiving a beam transmitted through the object arranging section to extract only a specified refraction angle component, and a sensor for detecting a beam extracted by the analyzer crystal.
