Abstract:
An x-ray radiation stabilization system comprising:an x-ray tube which emits x-ray radiation, said x-ray tube including;an anode;a cathode; and,a vacuum envelope housing the anode and the cathode;a high-voltage generator connected to the x-ray tube which supplies a high voltage electric potential between the cathode and anode such that an electron beam flows therebetween striking the anode to produce the x-ray radiation;a reference radiation detector which samples a representative portion of the x-ray radiation emitted by the x-ray tube and generates a signal in response to an intensity of the sampled x-ray radiation; and,a feedback circuit connected between the reference radiation detector and the high-voltage generator, which feedback circuit generates an error signal in response to the signal generated by the reference radiation detector, said error signal directing the high-voltage generator to modulate the high-voltage electric potential supplied to the x-ray tube such that in the x-ray radiation, fluctuation having a predetermined frequency range is substantially canceled.
