Patent ID: 8638903

Claim:
An X-ray imaging apparatus comprising: a splitting element that spatially splits X-rays generated by an X-ray generator; a first attenuation element on which X-rays split by the splitting element and passed through an object are incident; a second attenuation element on which X-rays split by the splitting element and passed through the object are incident, the second attenuation element being disposed adjacent to the first attenuation element; and a detecting unit configured to detect intensities of X-rays that have passed through the first attenuation element and the second attenuation element, wherein the first attenuation element and the second attenuation element are configured so that a transmission amount of X-rays continuously changes in accordance with a position at which the X-rays are incident, and wherein the first attenuation element and the second attenuation element are different from each other with respect to an amount of change or a characteristic of change in a transmission amount of X-rays in a direction of a displacement of the X-rays.
