Patent ID: 7346145

Claim:
An X-ray imaging system, comprising: means for irradiating a target object with an X-ray beam; an analyzer crystal splitting a transmitting X-ray beam of the object into a plurality of diffracted beams non-parallel to one another by simultaneous X-ray diffraction; a plurality of X-ray detectors which each detect a corresponding one of the diffracted X-ray beams; and a processor which arithmetically processes a plurality of signals output from the plurality of X-ray detectors; wherein: the analyzer crystal rotates with respect to the transmitting X-ray beam; and the processor obtains an image, in which a spatial differential of the phase shift and the phase shift of the transmitting X-ray beam caused by the object are both taken as contrast, using the plurality of diffracted X-ray beams that each the X-ray detectors detect at each rotational angle of the analyzer crystal.
