We have chosen to first apply this technology towards tracking catheters used in endovascular aortic stent-grafting. To demonstrate the feasibility of this concept, we have developed a system involving a custom catheter based transducer and performed an experiment in excised porcine tissue with a model aorta.
Abstract This work uses ultrasound signals to track the 3D location of a catheter. Our system pr... more Abstract This work uses ultrasound signals to track the 3D location of a catheter. Our system provides 3D coordinate data and not images. The coordinates can be registered with preoperative, 3D CT image data to provide a "GPS" like navigation system for catheter ...
