    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: A computed tomography imaging system includes an x ray tube (12, 212) that injects an x ray conebeam into an examination region (14). The x ray tube (12, 212) includes a rotating cylindrical anode (30, 230, 330, 430) having a target outer surface region. The cylindrical anode (30, 230, 330, 430) rotates about a longitudinally aligned cylinder axis (32). Electrons are accelerated toward a selected spot on the target outer surface region of the cylindrical anode (30, 230, 330, 430). Electrostatic or electromagnetic deflectors (64, 68) sweep the selected spot back and forth across the target outer surface region of the cylindrical anode (30, 330, 430). The imaging system further includes a rotating gantry (22) that revolves the x ray tube (12, 212) about the examination region (14) around a rotation axis that is parallel to the cylindrical axis, and an x-ray detector (16) arranged to detect x rays after said x rays pass through the examination region (14).
