An X-ray generation unit for generating X-rays, an X-ray imaging unit for performing X-ray imaging, and an X-ray imaging control unit for controlling X-ray imaging communicate information with one another via a communication line, to pick up a medical X-ray image. The X-ray generation unit receives X-ray imaging permission from the X-ray imaging control unit, and the X-ray imaging unit receives the X-ray imaging permission from the X-ray imaging control unit. The X-ray imaging control unit includes an X-ray imaging permission transmission unit for transmitting the X-ray imaging permission to the X-ray generation unit and the X-ray imaging unit, an X-ray imaging permission reception unit, an imaging condition determination unit for determining an imaging condition from an imaging order, an imaging permission condition determination unit for determining an imaging permission condition from the determined imaging condition, and a processing control unit for performing processing according to the imaging permission condition determined by the imaging permission condition determination unit.
