摘要: An ultrasonic transducer system for treating a portion of tissue. The includes frequency generator, an transducer, and transmitter element. receives AC voltage from the generator produces energy pulse at width. element is coupled to irradiating skin has chilled surface in contact with tissue acoustic aperture producing substantially collimated beam. beam width greater than 4 mm.
