摘要： A method for operating an electron beam system is presented. Further, an electron beam system, an X-ray tube and a CT system that implement the presented method are also described. The method includes generating an electron beam in an X-ray tube in an imaging system. Additionally, a current configuration corresponding to a particular view of the imaging system is identified. If the identified current configuration is within a determined range, a duty cycle of the electron beam for the particular view of the imaging system is modulated using pulse width modulation. Further, the modulated electron beam is focused towards a target.
