Abstract
An ultrasonic transducer assembly is disclosed having both transmit and receive circuitry integral to the transducer assembly for generating and receiving ultrasonic pulses. The ultrasonic transducer array which is integral with the transducer assembly preferably includes multi-layer transducer elements as transmit elements of the array and may include single layer transducer elements as receive elements. Also disclosed is an ultrasonic scanner utilizing the transducer assembly with integral transmit and receive circuitry to reduce the amount and complexity of interconnections between the transducer assembly and a scanner rack.
