description A novel cathode structure used for an X-ray tube disclosed by the present invention comprises a cathode master control grid and a single emitter grid, a support bracket is arranged in the cathode master control grid, a cathode emitter assembly is arranged above the support bracket, a cathode emitter lead is arranged at the bottom of the cathode emitter assembly, and the single emitter grid is connected with the cathode emitter lead. And a cathode main insulator is arranged at the bottom of the supporting bracket. According to the novel cathode structure for the X-ray tube, a bias voltage adding mode is that a ring-shaped voltage is added around the cathode emitter assembly, so that the functions of regulating and controlling tube current, emitting area size, quick closing and the like can be realized, and a matrix emitting structure of the cathode emitter is used; a plurality of cathode emitter lead structures are arranged on a cathode emitter assembly, and different control voltages at multiple points are ap
