Abstract
A transducer assembly, suitable for medical examinations, for generating an apodized sector shaped beam of energy. A transducer in the form of a crystal, has a ring-like structure on its face which apodizes the signal produced by the transducer by providing a greater amount of attenuation at the transducer's periphery than at the transducer's center.
