ABSTRACT:
An ultrasound transducer assembly includes an ultrasound transducer for transmitting and receiving ultrasound energy and one or more interface elements for conducting transmitted ultrasound energy from the transducer to a patient's body and for conducting received ultrasound energy from the patient's body to the transducer. At least one ultrasound-transmissive interface element is fabricated of a polymeric material. The material preferably has a sound speed that approximately matches the speed of sound in human tissue. The material comprises at least one primary rigid component material and at least one secondary component material, and has a Shore D durometer hardness value of greater than about 60D, and a sound speed of between about 1,450 meters/second and about 1,700 meters/second. The ultrasound-transmissive element fabricated of a polymeric material can be a protective lens cover, an ultrasound lens or lens element, an ultrasound-transmissive window or a sound pipe.
