Abstract

An ultrasonic transducer includes a transducer element having a backing element bonded thereto. The thickness of the backing element is selected to be less than or equal to half the length of an ultrasonic pulse, expressed in wavelengths of the center frequency of the pulse, so that the first reflection from the back side of the backing element is received by the transducer element before the primary pulse rings down. A method for mounting the transducer that reduces the formation of air bubbles includes the steps of forming a peaked mound and continually lowering the transducer to flatten the mound against the underside of the transducer.
