  • Patent number: 10893911
    Abstract: Systems, methods, and computer-readable media are provided. Some embodiments include obtaining image data of a subject and a medical device, the medical device including fiducial markers, wherein the image data includes three-dimensional image data. Information is generated representing a three-dimensional shape based on a planned insertion point for performing a medical procedure. A cropping process is applied to the image data to generate cropped image data based on the three-dimensional shape. In some embodiments, the cropped image data includes image data of at least two of the fiducial markers. Fiducial marker objects are detected within the cropped image data, and the fiducial marker objects are registered by matching a model of the fiducial markers with the fiducial marker objects.

  • Publication number: 20200375682
    Abstract: An apparatus, method, and system for a steerable medical instrument, configured to be used in conjunction with guided tools and devices under robotically controller medical procedures, including endoscopes, cameras, cutting tools and catheters. In one embodiment, the steerable instrument includes an elongate body (100), a control wire (110) arranged in a channel (104) of the elongate body and displaceable along the channel to bend the elongate body; and a controller (320) to selectively control drive forces applied to the control wire (110) under an actively controlled mode and a passively controlled mode. In the actively controlled mode, the controller actively bends at least part of the elongate body. In the passively controlled mode, the controller (320) decreases an amount of strain or an amount of displacement of the control wire, so that the control wire becomes compliant to external forces.
