Abstract:
A method for constructing a connection assembly for use in a multiple aperture ultrasonic transducer including an array of elements for transmitting or receiving signals, wherein each element is comprised of a plurality of segments, and the connection assembly for interconnecting the segments of each element and for connecting the segments to transmit/receive circuits to form the apertures of the array, comprising the steps of:superimposing an isolating layer on the segments of the array, forming a plurality of via openings through the isolating layer, at least one of the plurality of via openings being associated with at least one of the plurality of segments of the array and at least one of the plurality via openings exposing an area of at least one of the plurality of segments, superimposing a conductive layer on the isolated layer, the conductive layer having conductive paths interconnecting the respective areas of each segment exposed by the plurality of via openings by covering interior surfaces of the plurality of via openings and connecting the respective areas of each segment to the transmit/receive circuits to form the apertures of the array.
