Abstract: An ultrasound device including an ultrasonic transducer device having a plurality of transducer elements forming a transducer array is provided. Each transducer element includes a piezoelectric material disposed between a first electrode and a second electrode. One of the first and second electrodes is a ground electrode and the other of the first and second electrodes is a signal electrode. The ultrasound device further includes a cable assembly having a plurality of connective signal elements and a plurality of connective ground elements extending in substantially parallel relation therealong. Each connective element is configured to form an electrically-conductive engagement with respective ones of the signal electrodes and the ground electrodes of the transducer elements in the transducer array. The connective ground elements are alternatingly disposed with the connective signal elements across the cable assembly, to provide shielding between the connective signal elements.
