ABSTRACT:
An ultrasound transducer that allows transmission of pressure waves at a first frequency and reception of pressure waves at a second frequency. Each transducer element is formed by multiple layers of transducer material. A transceiver provides an excitation signal to the transducer and receives energy from the transducer. All of the layers are coupled to the transceiver during transmission so that all of the layers are activated. Some of the layers are decoupled from the transceiver during reception so that not all of the layers contribute to the received signal.
