とを特徴とするＸ線自動露出制御装置。 Automatically sets the imaging tube voltage based on the fluoroscopy tube voltage, collects a portion of the output of the X-ray fluorescence intensifier tube that converts the X-rays that have passed through the subject into an optical image, and converts that light into an electrical signal. In a phototimer-type X-ray automatic exposure control device that stops X-ray emission when the integral value of the signal reaches a predetermined value, in addition to the imaging tube voltage, the imaging tube current is adjusted according to the imaging tube voltage. An X-ray automatic exposure control device characterized by having an X-ray condition setting mechanism that automatically sets X-ray conditions.
