Abstract:
1. An X-ray imaging system comprising: an X-ray source operable to generate an X-ray beam; an X-ray receiver receiving the X-ray beam; a power generator generating power to the X-ray source to generate the X-ray beam; a grid disposed between a cathode and an anode of the X-ray source; a first pulse generator generating a first signal comprising first multiple pulses at a first pulse rate, each of the first multiple pulses having a pulse width; and a second pulse generator coupled to the grid and the power generator, the second pulse generator generating a second signal comprising second multiple pulses at a second pulse rate higher than the first pulse rate during each pulse width of the first multiple pulses, wherein the second signal is communicated to the grid to cause the X-ray beam to pulse on and off in accordance with the second signal during imaging.
