  • Publication number: 20250107701
    Abstract: Endoscopic systems and methods use a multi-view camera tool inside the body, including airways of a lung, to capture images, and use a combination of positional informational from EM and/or IMU sensors of the multi-view camera tool to estimate image depth and generate a three-dimensional (3D) point cloud volume of the patient anatomy. The 3D point cloud volume is generated from a known vantage point using stereoscopic images captured by the camera tool. This 3D structure generation may use a stereo image rectification algorithm. A machine learning algorithm may also be applied in place of, or in combination with, an image rectification algorithm to improve computational efficiency.

  • Publication number: 20250098937
    Abstract: A system for performing a surgical procedure includes an extended working channel (EWC) having a drive mechanism, a catheter having a camera and an electromagnetic sensor, and a workstation including a memory storing instructions, which when executed by a processor cause the processor to determine a location and an orientation of a distal end of the EWC, receive real-time images of the patient's anatomy from the camera, identify a centerpoint of a lumen within the received real-time images, articulate the distal end of the EWC using the drive mechanism to align the distal end of the EWC with the identified centerpoint, and instruct the drive mechanism to reduce tension on the distal end of the EWC to permit the distal end of the EWC to deflect when contacting walls of the lumen if a diameter of the lumen approximates an outer diameter of the EWC.
