ABSTRACT:
A lamp emits pulse-shaped visible light when a wait period begins. If a radiation emission switch is not pressed in the wait period, X-ray radiation is not emitted from an X-ray source, and no charges are accumulated in photoelectric conversion elements of an X-ray imaging apparatus. In a non-read period, although signals are sequentially read from the photoelectric conversion elements, an output signal does not change. When the radiation emission switch is pressed in synchronization with a radiation-induced signal in a certain wait period, the X-ray source emits X-rays. After irradiation of X-rays, a photoelectric conversion period transitions to an actual read period. In the photoelectric conversion period, X-rays are emitted and transmitted X-ray information of a patient are accumulated in the photoelectric conversion elements of the X-ray imaging apparatus. In the actual read period, the accumulated information is read.
