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 displaying on a user interface.
