Abstract:
1. A method for providing a backing member for an acoustic transducer array, said method comprising the steps of: providing a contact block member comprising an acoustically absorbent material having a plurality of individual conductive contact members of a pyramidal shape embedded therein such that said contact block member includes, at a first surface thereof, a plurality of contact pads of a first pattern formed by one end of said contact members, and includes, at a second, opposite surface thereof, a plurality of contact pads also of said first pattern formed by the opposite ends of said contact members, said contact pads of said first and second surfaces being connected together by conductive through conductors formed by said contact members, and said contact members being spaced apart from one another with a spacing corresponding to the pitch of the transducer array; affixing an interconnection printed circuit board to one of said first and second surfaces so as to enable electrical signal to be supplied to the transducer array through the contact members; and affixing a carrier layer to said interconnection printed circuit board in alignment with said contact block member.
