摘要：
A surgical navigation system including an ultrasound catheter is disclosed herein. The ultrasound catheter includes a flexible catheter housing defining a distal end, a transducer array disposed at least partially within the catheter housing, and a motor coupled with the transducer array. The motor is configured to rotate the transducer array in order to image a three-dimensional volume. The ultrasound catheter also includes a tracking element adapted to provide an estimate of a position and/or orientation of the distal end of the catheter housing. The tracking element is disposed within the catheter housing and immediately adjacent to the distal end.
