A device for ultrasonic imaging, and methods for the use and manufacture thereof, particularly of small coronary vessels comprises an elongate member with a distal end that can be positioned within a small vessel of a patient's body while a proximal end is located outside the body, a transducer located at a distal end of the elongate member and operable to scan the distal coronary vessels with ultrasonic pulses, and a signal processor connected to a proximal end of the elongate member and to the transducer for generating and receiving pulses to and from the transducer. A motor may also be connected to the proximal end of the elongate member for rotating the transducer. <IMAGE> |
