Abstract
According to a radiographic apparatus of this invention, parameters obtained on an assumption that an X-ray tubeis moved Wd×m, which is an integral multiple of pixel pitch Wd, in a Bdirection opposite to Bdirection which is a direction of movement by Y-direction adjust screws of a moving mechanism, are corrected as parameters obtained when X-rays are emitted from the X-ray tubein a state of a gridhaving been moved Wd×m by the Y-direction adjust screws. This allows only the gridto be moved without moving the X-ray tube. Therefore, parameters equivalent to the parameters which should be obtained when the X-ray tubeis moved are obtained by moving the grid, and position shifting can be reduced.
