Abstract
A cylindrical ultrasonic transducer (36) is disclosed. The transducer includes a cylindrical main element (38) provided with a plurality of ring-shaped secondary elements (40 and 42) that are triangular in cross section. By controlling the number, geometry, and construction of the secondary elements, substantially any desired ultrasonic emission pattern can be produced while maintaining a low overall transducer profile.
