Abstract
A method for generating a fast rise-time X-ray pulse includes the steps of providing an n-phase x-ray generator, the x-ray generator including an n-phase transformer having at least one primary winding and at least one secondary winding per phase, and providing n sections of rectifiers, each rectifier having at least a fast pulse rise-time mode and a n-phase ripple flat-top mode. According to the method, at least a first capacitor is charged in each of the n sections of rectifiers at a ripple of less than n-phases to create a fast leading edge of the fast rise-time pulse, and at least a second capacitor is charged in each of the n sections or rectifiers at an n-phase ripple to create a substantially flat-top of the fast rise-time pulse.
