Patent number: 10307115Abstract: A system for cone beam computed tomography of an extremity has an x-ray source and a digital radiographic detector both revolved about a central imaging axis so that the detector moves at least partially around a first extremity of a patient and, if the extremity is the leg of the patient, the detector moves between the legs of the patient. The detector path has a radial distance less than that of the source path. A housing that encloses the source and detector includes a pivoting door to allow sideways access for the patient's leg to be placed at the central imaging axis.Type: GrantFiled: June 14, 2018Date of Patent: June 4, 2019Assignee: Carestream Health, Inc.Inventors: John Yorkston, Robert J. Asento, Jeffrey H. Siewerdsen, David H. Foos

Patent number: 10010295Abstract: An apparatus for cone beam computed tomography of an extremity has a digital radiation detector and a first device to move the detector along a circular detector path extending so that the detector moves both at least partially around a first extremity of the patient and between the first extremity and a second, adjacent extremity. The detector path has radius R1 sufficient to position the extremity approximately centered in the detector path. There is a radiation source with a second device to move the source along a concentric circular source path having a radius R2 greater than radius R1, radius R2 sufficiently long to allow adequate radiation exposure of the first extremity for an image capture by the detector. A first circumferential gap in the source path allows the second extremity to be positioned in the first circumferential gap during image capture.Type: GrantFiled: February 6, 2017Date of Patent: July 3, 2018Inventors: John Yorkston, Robert J.
