    Abstract: A transmission x-ray tube comprising an end window hermetically sealed to a flexible coupling. The flexible coupling can allow the window to shift or tilt in one direction or another direction to allow an electron beam to impinge upon one region of the window or another region of the window.A method of utilizing different regions of an x-ray tube target by tilting an x-ray tube window at an acute angle with respect to an electron beam axis to cause an electron beam to impinge on a selected region of the window and tilting the window in a different direction to allow the electron beam to impinge on a different selected region of the window.

    Abstract: An X-ray tube anode target assembly having a support shaft connected to a pivot assembly and a movable anode target surface disposed at one end of the support shaft. A first drive assembly is operably arranged with respect to the support shaft to provide oscillatory motion to the anode target about a first axis substantially parallel to the support shaft and drive cylinder operably arranged with respect to the contact element to provide a pivoting motion to the support shaft. A second drive assembly is operably arranged with respect to the drive cylinder to provide an oscillatory motion to the drive cylinder, the second drive cylinder having a cam portion to provide linear motion to the support shaft parallel to the first axis. The target surface is maintained at a substantially constant angle of impingement and maintains a substantially fixed distance from a cathode during target motion.

    Abstract: A distributed X-ray source (3) and an imaging system (1) comprising such an X-ray source (3) are proposed. The X-ray source (3) comprises an electron beam source arrangement (19) and an anode arrangement (17). The electron beam source arrangement (19) is adapted to emit electron beams (24) towards at least two locally distinct focal spots (27) on the anode arrangement (17). Therein, the X-ray source is adapted for displacing the anode arrangement (17) with respect to the electron beam source arrangement (19). While the provision of a plurality of focal spots allows acquisition of projection images under different projection angles thereby allowing reconstruction of three-dimensional X-ray images e.g. in tomosynthesis application, a displacement motion of the anode arrangement (17) with respect to the electron beam source arrangement (19) may allow for distributed heat flux to the anode arrangement thereby possibly reducing cooling requirements.

    Abstract: It is described an X-ray tube (205), in particular for use in computed tomography, comprising an electron source (250), for generating an electron beam (255), 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 deflection, and an anode (206), which is arranged 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.

    Abstract: An x-ray tube (10) includes an anode (14) connected to a mechanical drive (36). The mechanical drive oscillates the anode in a gyrating motion relative to a body of the x-ray tube. The mechanical drive is operatively connected to the anode via a bellows assembly (16) and is capable of rocking the anode in two axes simultaneously. The preferred anode is shaped in a shperical section (28) providing a fixed focal distance between the anode and a cathode (20) regardless of relative position of the anode within the body. An electron shield (40) is disposed between the cathode and the anode and has an opening along a preferred path for electron travel. Improved heat exchange is provided by applying a heat transfer agent to an obverse side of the anode which is preferably located outside of a vacuum envelope (18) defined by the x-ray tube body, the anode, and the bellows.
