Abstract

An ultrasound transducer includes a transducer array having a plurality of transducer elements. The transducer array has a first side and a second side. Further, one or more ground electrodes are disposed on the first side of the transducer array, and one or more signal electrodes are disposed on the second side of the transducer array. Moreover, an acoustic backing structure is operatively coupled to the plurality of transducer elements of the transducer array. Also, a plurality of electrical traces is routed on a surface of the acoustic backing structure and operatively coupled to at least one of the one or more signal electrodes and one or more ground electrodes.
