Method of manufacturing a curvilinear array of ultrasonic transducers
First Claim
1. A method of manufacturing a convex array of ultrasonic transducers, comprising the following steps in the stated order:
- bonding a flexible printed circuit board having electrode lead patterns to a portion of a rear surface of a flat transducer plate;
bonding said rear surface of said transducer plate having said electrode lead patterns bonded thereto to one side of a flexible backing plate to sandwich said flexible print cirucit board between said flexible backing plate and said transducer plate;
cutting through said transducer plate and said flexible printed circuit board at least through to the flexible backing plate between said electrode lead patterns to produce an array of transducer elements; and
bending said flexible backing plate around a convex surface of a backing base and bonding the other side of said flexible backing plate to said convex surface.

Abstract
A curvilinear array of ultrasonic transducers primarily for use in a medical diagnostic apparatus by which divergent ultrasonic beams are transmitted without resorting to sector scanning techniques to steer the ultrasonic beam. The curvilinear array of ultrasonic transducers includes a flexible transducer assembly bonded to a curvilinear surface of backing base. The flexible transducer assembly includes a flexible backing plate and an array of ultrasonic transducers elements disposed on the flexible backing. The array is formed of a transducer plate having grooves cut through to the flexible backing plate to isolate the transducer elements.
