An X-ray tube and a grid can be easily aligned. An X-ray imaging device of the present invention includes an imaging unit configured to capture an X-ray image, a first moving unit configured to move a grid relative to an imaging surface of the imaging unit, the grid being configured by lead foil strips disposed in an oblique array, an acquisition unit configured to acquire information indicating a focal position of the grid that has been moved by the first moving unit, and a second moving unit configured to move an X-ray irradiation unit configured to irradiate the imaging unit with X-rays to the focal position of the grid based on the information acquired by the acquisition unit. |
