According to one embodiment, an X-ray imaging apparatus includes an X-ray image acquisition unit, a control system and a display processing part. The X-ray image acquisition unit is configured to acquire X-ray image data of an object by using at least one imaging system. The control system is configured to control the imaging system to acquire frames of X-ray image data corresponding to mutually different not less than three directions by reciprocating the imaging system. The display processing part is configured to generate stereoscopically visible image data with lining up the frames of the X-ray image data in a display order different from an acquisition order of the frames of the X-ray image data. The display order is according to a moving direction of the imaging system.
