  • MOTION COMPENSATION PLATFORM FOR IMAGE GUIDED PERCUTANEOUS ACCESS TO BODILY ORGANS AND STRUCTURES
    Publication number: 20210059762
    Abstract: A method and a system for registering real-time intra-operative image data of a body to a model of the body, the method comprising, segmenting a plurality of image data of the body obtained using a pre-operative imaging device; constructing the model of the body from the segmented plurality of image data; identifying one or more landmark features on the model of the body; acquiring the real-time intra-operative image data of the body using an intra-operative imaging device; and registering the real-time intra-operative image data of the body to the model of the body by matching one or more landmark features labelled on the real-time intra-operative image data to one or more corresponding landmark features on the model of the body, wherein the one or more landmark features comprises a superior and an inferior pole of the body.

  • Robotic device for use in image-guided robot assisted surgical training
    Patent number: 8764448
    Abstract: A robotic device for use in image-guided robot assisted surgical training, the robotic device comprising a manual interface structure configured to simulate handling of a surgical tool; a translational mechanism for translational motion of the manual interface structure; a rotational mechanism for rotational motion of the manual interface structure; and a spherical mechanism configured to decouple the orientation of the manual interface structure into spatial coordinates, wherein a linkage between the rotational mechanism, the rotational mechanism and the spherical mechanism, and the manual interface structure are disposed on opposing sides of an intersection of a pitch axis and a yaw axis of the spherical mechanism.
