  • Extremity imaging apparatus for cone beam computed tomography
    Patent number: 10405812
    Abstract: An apparatus for cone beam computed tomography can include a support structure, a scanner assembly coupled to the support structure for controlled movement in at least x, y and z orientations, the scanner assembly can include a DR detector configured to move along at least a portion of a detector path that extends at least partially around a scan volume with a distance D1 that is sufficiently long to allow the scan volume to be positioned within the detector path; a radiation source configured to move along at least a portion of a source path outside the detector path, the source path having a distance D2 greater than the distance D1, the distance D2 being sufficiently long to allow adequate radiation exposure of the scan volume for an image capture by the detector; and a first gap in the detector path.
    Type: Grant
    Filed: August 21, 2017
    Date of Patent: September 10, 2019
    Assignees: Carestream Health, Inc., The Johns Hopkins University
    Inventors: Michael A. Litzenberger, Peter A. Newman, John Yorkston, Andrew J. Hartmann, Jeffrey H. Siewerdsen, Douglas M. Csaszar
