An inspection sorting apparatus includes an X-ray tube with an anode electrode and a cathode electrode, a tank housing the X-ray tube and having insulation oil contained therein, and the anode electrode and the cathode electrode are supplied with a predetermined voltage to generate X-ray. An inspection sorting apparatus has an abnormal discharge determination unit, an LCD display, and a notification control unit. The abnormal discharge determination unit individually detects a first abnormal discharge which is an abnormal discharge inside the X-ray tube, and a second abnormal discharge which is an abnormal discharge inside the tank outside the X-ray tube. The LCD display outputs notification information prompting an administrator to replace the X-ray tube or the tank. The notification control unit causes the LCD display to output the notification information in accordance with a detection result from the abnormal discharge determining unit.

Systems and methods are provided for generating X-ray pulses during X-ray imaging. A high voltage of an X-ray tube is automatically switched off. The tube voltage decays and upon reaching a predefined threshold value of the tube voltage or a predefined waiting time after switching off the high voltage, a grating voltage of a grating arranged between an emitter and an anode of the X-ray tube is automatically switched on. No electrons reach the anode from the emitter, and the tube current drops to the value zero.
