Method of manufacturing a curvilinear array of ultrasonic transducers

摘要

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.
