<p>Provided is an X-ray imaging device in which only a grid (6) can be moved without moving an X-ray tube (2) by correcting a parameter obtained when it is assumed that the X-ray tube (2) is moved by Wd×m that is an integral multiple of a pixel pitch Wd in a B- direction opposite to a B+ direction that is the direction of movement by a Y-direction adjustment screw of a moving mechanism as a parameter obtained by applying an X-ray from the X-ray tube (2) in a state in which the grid (6) is moved by Wd×m by the Y-direction adjustment screw. Accordingly, the parameter equal to a parameter to be obtained when the X-ray tube (2) is moved can be obtained by moving the grid (6), resulting in a reduction in displacement.</p> |
