ABSTRACT:
An ultrasonic transducer has two intersecting linear arrays defining a cross shaped transducer assembly having four arms and an intersecting area. A plurality of transverse grooves form transducer elements in the arms. Coaxial transducer elements are formed in the intersecting area. Each transducer element has its signal electrode on a common side of the transducer. One or both of the intersecting linear arrays may be curved along its longitudinal axis thus allowing the transducer to be mounted on cylindrical or spherical surfaces.
