A coupling pad can be used with a transducer element. Ultrasound produced by the transducer element can be propagated through the coupling pad to a patient. In one arrangement, the pad is a pouch containing a pliant substance. In other arrangements, the pad is a somewhat solid member formed of a material that transmits ultrasound waves efficiently. The pad may be configured to fit between a patient's skin and a transducer element so that output from the transducer element passes through the pad to a treatment site of the patient. |
