    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: Disclosed is a reusable microfocus X-ray tube adapted to generate a relatively large number of X-rays in a relatively short period of time using a narrowly focused electron beam. The X-ray tube comprises means for producing a dense, narrow electron beam (16, 18), a target anode (22), and means for moving the target anode (24, 28) so that it is stationary during production of the X-rays but a fresh portion of the surface of the target anode is presented to the electron beam each time the X-ray tube is used. The target anode is preferably in the form of a ribbon.

    Abstract: An X-ray generator including a cathode, an anode provided with two X-ray generation zones, a casing in which the cathode and anode are accommodated, two air cylinders for causing the anode to move, two linear guides for guiding the movement of the anode, and a bellows serving as a seal member. The air cylinders and the linear guides are provided at different positions on a surface orthogonal to a center axis of the bellows. The air cylinders and the linear guides are provided uniformly in relation to the center axis.

    Abstract: A x-ray tube comprising an anode sealed to a flexible coupling. The flexible coupling can allow the anode to deflect or tilt in various directions to allow an electron beam to impinge upon various selected regions of an anode target.A method of utilizing different regions of an x-ray tube target by tilting or deflecting an x-ray tube anode to cause an electron beam to impinge on a selected region of the target.

    Abstract: An X-ray tube anode target assembly (101) having a support shaft (107) connected to a pivot assembly (109) and a movable anode target (105) having a target surface (106) disposed at one end of the support shaft and a contact element (108) disposed at the opposite end of the support shaft. A first drive assembly (115) 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 a drive cylinder (125) is operably arranged with respect to the contact element to provide a pivoting motion to the support shaft. A second drive assembly (127) is operably arranged with respect to the drive cylinder to provide an oscillatory motion to the drive cylinder, the second drive cylinder being further configured to provide a linear motion 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 (103) during target motion.
