Abstract
An ultrasound transducer for use in intravascular ultrasound (IVUS) imaging systems including a single crystal composite (SCC) layer is provided. The transducer has a front electrode on a side of the SCC layer; and a back electrode on the opposite side of the SCC layer. The SCC layer may have a bowl shape including pillars made of a single crystal piezoelectric material embedded in a polymer matrix. Also provided is an ultrasound transducer as above, with the back electrode split into two electrodes electrically isolated from one another. A method of forming an ultrasound transducer as above is also provided. An IVUS imaging system is provided, including an ultrasound emitter and receiver rotationally disposed within an elongate member; an actuator; and a control system controlling emission of pulses and receiving ultrasound echo data associated with the pulses. The ultrasound emitter and receiver include an ultrasound transducer as above.
