Abstract:
1. An ultrasonic transducer assembly comprising: a transducer array comprising a number of spaced transducer elements; at least one printed circuit including a plurality of stepped trace layers arranged in a staircase fashion such that an edge of a top trace layer of the printed circuit is position farther away from the transducer elements than an edge of a bottom trace layer, wherein each layer has a plurality of conductive traces with a portion of the traces in each layer aligned with and electrically coupled to a corresponding transducer element via a conductive interconnection and wherein the portions of the traces in each trace layer that are aligned with the transducer elements have a pith that is greater than a pitch between adjacent transducer elements and wherein the traces that are interleaved have a pitch that is less than the, pitch between, adjacent traces, in each trace layer.
