Abstract
An X-ray source system for a CT scanner includes a plurality of X-ray sources, wherein each X-ray source of the plurality is provided with a cathode from which an electron beam is emitted, an anode to receive the electron beam and at least one grid electrode, wherein the grid electrodes are configured to selectably block radiation from said X-ray sources; a high voltage generator for applying voltage to the plurality of X-ray sources, wherein each of the plurality of X-ray sources are configured to present substantially the same load to the high voltage generator; a grid modulator configured to apply voltage to grid electrodes of each of the plurality of X-ray sources in turn; and a controller for controlling the grid modulator so that only one of the plurality of X-ray sources emits radiation at any one time.
