ABSTRACT:
An X-ray imaging apparatus includes an X-ray intensity designation unit which designates an emitted X-ray intensity of X-rays applied to a target, an X-ray exposure control unit which compares a predetermined recommended X-ray intensity with the emitted X-ray intensity designated by the X-ray intensity designation unit to determine whether the emitted X-ray intensity becomes equal to or more than the recommended X-ray intensity, and a warning generating unit which generates a warning signal indicating that the emitted X-ray intensity becomes equal to or more than the recommended X-ray intensity, on the basis of the determination made by the X-ray exposure control unit.
