  • System and method for artifact reduction in an image
    Patent number: 11756242
    Abstract: Selected artifacts, which may be based on distortions or selected attenuation features, may be reduced or removed from a reconstructed image. Various artifacts may occur due to the presence of a metal object in a field of view. The metal object may be identified and removed from a data that is used to generate a reconstruction.
    Type: Grant
    Filed: October 4, 2021
    Date of Patent: September 12, 2023
    Assignee: Medtronic Navigation, Inc.
    Inventors: Patrick A. Helm, Jeffrey H. Siewerdsen, Ali Uneri, Wojciech Zbijewski, Xiaoxuan Zhang, Joseph W. Stayman, IV

  • Computed tomography with resolution recovery
    Patent number: 7852980
    Abstract: A system and method for recovering resolution in an x-ray computed tomography system. The system includes an x-ray source, a two-dimensional sensing array, and a controller. The x-ray source projects an x-ray beam towards subject. The x-ray source includes an anode and a cathode, where the anode has a target for directing the x-ray beam. A two-dimensional sensing array receives an x-ray beam through the subject to generate an image. The target of the anode causes a shift variant blur of the x-ray beam received by the sensing array due to the angle between the target and the sensing array. The controller is in communication with the sensing array to control acquisition and processing of the image. The controller is configured to adjust for the shift variant blur of the x-ray beam.
