Abstract: An X-ray tube (260) is provided which is adapted to generate X-ray beams (258). The X-ray tube may comprise electrostatic grids (256) for focal spot deflection in x-direction, wherein the electrostatic grids are mounted on either side of the cathode (250). Further the X-ray tube may comprise electromagnetic coils (260) for focal spot deflection in y-direction, wherein said electromagnetic coils forming a dipole, are mounted external to the X-ray tube and are positioned between the cathode and the target of the anode (206), so that the electron beam (255) passes between its poles. The electrostatic grids and the electromagnetic coils are arranged separately from each other and provide for a combination of electrostatic x-deflection in tandem with electromagnetic z-deflection.

Abstract: An x-ray tube (24) includes an anode (42) defining a target. A cathode assembly (40) is in operative relationship with the anode to produce x-rays (56). An evacuated envelope (35) encloses the anode and cathode. The evacuated envelope includes a metal frame portion (39). The material comprising the metal frame portion has a backscatter coefficient. An x-ray transmissive window (41) is joined in a vacuum tight manner to the metal frame portion of the evacuated envelope. The material comprising the x-ray transmissive window has a backscatter coefficient. A backscatter layer (90) is deposited on the x-ray transmissive window and the metal frame portion of the evacuated envelope around the x-ray transmissive window. The backscatter layer has a backscatter coefficient greater than the backscatter coefficient of both of the window and the metal frame.

Abstract: An X-ray tube is provided adapted to generate X-ray beams, comprising a first and a second deflection device mounted external or internal to the X-ray tube between a cathode and an anode in a diagonal manner for focal spot deflection in a combined x- and y-direction. The first and second deflection devices are triggered alternately such that only one deflection device is activated at a time. The first and second deflection devices may be triggered according to a predetermined switching sequence, e.g. producing a predetermined deflection pattern of the focal spot. Thereby, an improved x- and z-flying focal spot methodology is provided.
