摘要： The invention provides an X-ray apparatus and an X-ray measurement method that can increase sensitivity to a positional shift of an X-ray as compared with related art.An X-ray apparatus includes a splitting element configured to spatially split an X-ray from an X-ray generator and form an X-ray beam; a detector configured to detect an intensity of the X-ray beam, which has been split by the splitting element and has passed through a detection object, the detector including a plurality of pixels; and an absorbing element arranged at a boundary of two pixels from among the plurality of pixels included in the detector and configured to absorb part of the X-ray beam. The X-ray beam is configured to discretely irradiate the two pixels of the detector.
