摘要： An X-ray imaging apparatus includes a multi X-ray source which includes a plurality of X-ray focuses to generate X-rays by irradiating X-ray targets with electron beams, a detector which detects X-rays which have been emitted from the multi X-ray source and have reached a detection surface, and a moving mechanism for moving the multi X-ray source within a plane facing the detection surface. The X-ray imaging apparatus acquires a plurality of X-ray detection signals from the detector by causing the multi X-ray source to perform X-ray irradiation while shifting the positions of a plurality of X-ray focuses which the detector has relative to the detection surface by moving the multi X-ray source using the moving mechanism. The apparatus then generates an X-ray projection image based on the plurality of X-ray detection signals acquired by the detector.
