CATHETER APPARATUS AND METHOD FOR TWO-DIMENSIONAL ULTRASONICEXAMINATION IN BLOOD VESSEL

摘要

Catheter apparatus provides for high resolution intravascular imaging to assist indovascular lesions and to monitor the results of interventional therapy. An ultrasonic transducer (52) is carried by the distal end of a catheter adapted for insertion into a vessel, and either the transducer or another element is rotated and/or moved longitudinally relative to the catheter to image different portions of the vessel.
