Abstract
Ultrasonic apparatus, system and method for high resolution intravascular imaging to assist indovascular lesions and to monitor the results of interventional therapy. An ultrasonic transducer 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 translated relative to the catheter to image different portions of the vessel.
