  • X-ray tube having a rotating and linearly translating anode
    Patent number: 8259905
    Abstract: The X-ray tube having a rotating and linearly translating anode includes an evacuated shell having a substantially cylindrical anode rotatably mounted therein. The substantially cylindrical anode may be rotated through the usage of any suitable rotational drive, and the substantially cylindrical anode is further selectively and controllably linearly translatable about the rotating longitudinal axis thereof. A cathode is further mounted within the evacuated shell for producing an electron beam that impinges on an outer surface of the substantially cylindrical anode, thus forming a focal spot thereon. X-rays are generated from the focal spot and are transmitted through an X-ray permeable window formed in the evacuated shell.
    Type: Grant
    Filed: July 22, 2010
    Date of Patent: September 4, 2012
    Assignee: King Fahd University of Petroleum and Minerals
    Inventors: Jihad Hassan Al-Sadah, Nabil Maalej, Ezzat Abbas Mansour
