According to one embodiment, an X-ray imaging apparatus includes an X-ray image acquisition part, a control system and a display processing part. The X-ray image acquisition part is configured to acquire X-ray image data of an object 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 directions by moving the imaging system. At least one of the frames of the X-ray image data are acquired during a movement of the imaging system. The display processing part is configured to generate stereoscopically visible image data based on the frames of the X-ray image data.
