  • Publication number: 20240216010
    Abstract: Guided percutanous device and method for providing visual representations of organ registration and tracking during a guided percutaneous procedure using an electromagnetic tracking (EMT) system comprising an EMT field generator and tracker defining an EMT coordinate system, a catheter with a EMT sensor for placing in the organ to indicate a percutaneous procedure target, a needle with an EMT sensor, an ultrasound (US) probe with an EMT sensor, and an electronic data processor configured for carrying out the steps of: loading preoperative imaging data; receiving 3D poses of the catheter, needle and US probe from the EMT; receiving intraoperative imaging data; calculating transformation matrices and multiplying said matrices to transform said imaging data and needle pose to a catheter pose; generating a visual representation of the transformed imaging data and needle pose for displaying on a user interface; generating a visual representation of the transformed registered preoperative imaging data for displayin

  • Publication number: 20240216073
    Abstract: Guided percutaneous uncertainty mapping device and method for providing visual representations of an uncertainty map with respect to an organ during a guided percutaneous procedure using an electromagnetic tracking (EMT) system comprising an EMT field generator and tracker, a catheter with a EMT sensor for placing in the organ to mark a percutaneous procedure target, and a needle with an EMT sensor and an electronic data processor configured for carrying out the steps of: receiving an indication of a percutaneous procedure target; receiving three-dimensional (3D) positions and orientations of the catheter and the needle tracked in real-time from the EMT system; estimating the uncertainty of the received position and orientation of the needle; estimating the uncertainty of the received position and orientation of the catheter: estimating a trajectory uncertainty of the needle departing from a current position and orientation of the needle; generating a visual representation of the estimated trajectory uncertai
