  • X-ray generator with x-ray tube voltage regulation for maintaining the x-ray tube current at a maximum value
    Patent number: 5329568
    Abstract: An x-ray generator includes an x-ray tube voltage regulation system which automatically adapts to line impedance and fluctuations in the network voltage, so as to maintain the x-ray tube current at a maximum value. The x-ray tube current is set by the x-ray tube voltage, the x-ray tube current is regulated so that a maximally allowable line voltage drop is not upwardly exceeded. The x-ray tube current, consequently, always has its maximum value, given the prevailing circuit conditions, so that the tube power is also at a maximum value. The current is set so as to achieve a desired mAs product, which is in turn determined by the radiation dose which the operator desires.
