    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.

    摘要： An X-ray imaging apparatus is provided with a multi X-ray source and a collimator in which a plurality of slits for X-rays to pass through are two-dimensionally formed, the size and position of the slits being adjustable. A control unit, as a first control mode, controls the size and position of the slits to move an examination region in parallel, when an X-ray source is changed to a different X-ray source, such that the examination directions are parallel before and after the change. Also, the control unit, as a second control mode, controls the size and position of the slits to rotate the examination direction, when an X-ray source is changed to a different X-ray source, such that the center of the examination regions is the same before and after the change.
