  • Registration and motion compensation for patient-mounted needle guide
    Patent number: 11202652
    Abstract: Exemplary methods, apparatus, and systems are disclosed for automated registration and motion compensation of patient-mounted needle guide medical devices using fiducial markers, and processing algorithms where a re-registration step is provided. These methods, apparati, and systems adaptively compensate for the displacement of the medical device and/or target location due to the patient movement or internal organ motion.
    Type: Grant
    Filed: August 3, 2018
    Date of Patent: December 21, 2021
    Assignees: Canon U.S.A., Inc., The Brigham and Women's Hospital Inc.
    Inventors: Junichi Tokuda, Laurent Chauvin, Kemal Tuncali, Nobuhiko Hata, Santosh Ganesan, Barret Daniels, Brian Ninni, Franklin King
  • Fiducial markers, systems, and methods of registration
    Patent number: 10420626
    Abstract: Exemplary methods, apparatus, and systems are provided for automated detection and registration of medical images using fiducial markers and processing algorithms. By either clustering fiducial markers having a different number, size, shape, configuration, or material property or by using fiducial markers arranged in a ring shape, wherein their arrangement is asymmetric, and then applying a feature extraction to extract the fiducial marker objects, and registering the fiducial marker objects with a model of the fiducial frame, automatic registration can be achieved.
