  • Grid control system for eliminating soft radiation emissions from an X-ray tube
    Patent number: 7916837
    Abstract: A system and method for controlling the radiation emissions from an x-ray tube having an anode, a cathode, and a grid is disclosed. The system and method uses a continuous high voltage across the cathode and the anode of the x-ray tube, so that a high voltage is continuously applied to the x-ray tube between the cathode and the anode. The flow of electrons between the cathode and the anode is then controlled by a pulsed high voltage to the grid, the pulsed high voltage being of substantially the same magnitude as the continuous high voltage and being switched at a frequency of about one microsecond to provide alternate the polarity of the switched high voltage to the grid, so that voltage between the cathode and the anode is switched by the voltage applied to the grid by the source of pulsed high voltage, so that soft radiation emissions from the x-ray tube are minimized or eliminated.
