    Abstract: A sealed-off X-ray tube having a convex target surface facing an electron beam source and carried by a rigid support mounted for rotary pivotal motion about a fixed pivot point. A bellows is sealed vacuum tight to the target and to the wall of the tube around the pivot point so that the target, the bellows, and the envelope of the tube form a closed surface. Conduits extend through the pivotal bearing to direct the flow of cooling fluid against the back surface of the target and carry the fluid away. The target surface is spherically convex with a center of curvature at the pivot point. The axis of the target precesses about the axis of the tube but the target does not rotate on its own axis. The target may be moved manually or by motor and with a linear, circular or spiral motion. Because of the curvature of the target, the electron optical forces are substantially unaffected by the precessing motion, and virtually constant X-ray beams radiate through windows of the tube.

    Abstract: A high flux X-ray tube anode target assembly (101). The assembly includes a support shaft (107) connected to a pivot assembly (109). The assembly further includes a movable anode target (105) having a target surface (106) disposed at one end of the support shaft. The target surface includes a single radius of curvature. The radius of curvature extends from a pivot point (110). The assembly also includes a drive member (119) operably arranged with respect to the support shaft to provide motion to the anode target. The assembly is configured to maintain a substantially fixed distance between the pivot point and the target surface.

    Abstract: It is described an X-ray tube (205) comprising an electron source (250), adapted for generating an electron beam (255) projecting along a beam axis, an electron deflection device (256) for deflecting the generated electron beam (255), a control unit (257) being coupled to the electron deflection device (256) for spatially controlling the beam axis, and an anode (206), which is arranged within the beam axis such that the electron beam (255) impinges onto a focal spot of a surface of the anode (206). Thereby the anode (206) is movable along a z-axis in an oscillating manner, the surface of the anode (206) is oriented oblique with respect to the z-axis, and the control unit (257) is adapted to spatially control the focal spot (255 a) in such a manner that the focal spot moves essentially in a discrete manner between a first focal spot position (106a, 406a) having a first z-coordinate and a second focal spot position (106b, 406b) having a second z-coordinate being different from the first z-coordinate. It is further described a computed tomography system (100) being equipped with the X-ray tube (205) and a method for operating the X-ray tube (205).
