  • Apparatus for reducing kV-dependent artifacts in an imaging system and method of making same
    Patent number: 7869572
    Abstract: An x-ray tube includes a vacuum chamber, a cathode positioned within the vacuum chamber and configured to emit electrons, and an anode positioned within the vacuum chamber to receive the electrons emitted from the cathode and configured to generate a beam of x-rays from the electrons. The x-ray tube further includes a window positioned to pass the beam of x-rays therethrough, an electron collector structure having an aperture formed therein to allow passage of x-rays therethrough, and a layer attached to the electron collector structure and configured to at least partially absorb or reduce diffraction of x-rays that contact the layer.
    Type: Grant
    Filed: May 7, 2008
    Date of Patent: January 11, 2011
    Assignee: General Electric Company
    Inventors: Donald Robert Allen, Brian Lounsberry, James J. VanBogart

    Patent number: 7796737
    Abstract: An x-ray tube includes a cathode positioned within a vacuum chamber and configured to emit electrons. The x-ray tube includes an anode positioned within the vacuum chamber to receive electrons emitted from the cathode and configured to generate a beam of x-rays from the electrons, a window positioned to pass the beam of x-rays therethrough, and an electron collector structure attached to the x-ray tube having an aperture formed therethrough to allow passage of x-rays therethrough. The aperture is shaped to prevent diffracted x-rays from combining with the beam of x-rays passing through the window.
