Abstract
An ultrasound therapy system and method for providing therapeutic treatment to tissues using multiple, user-selectable frequencies generated from a single applicator sound head. The multi-frequency ultrasound therapy system and method includes a generator/control unit having a microprocessor for controlling and monitoring the generation and output of ultrasonic energy. A precision oscillator is connected to the microprocessor, and wave shaping circuitry is also provided to generate a wave-form for amplification by an output amplifier. The amplified high frequency wave-form is supplied to and drives an applicator sound head at an appropriate frequency for producing the desired therapeutic ultrasonic waves for treatment. Bonded to a cup member and positioned within the applicator sound head is a transducer crystal which converts high frequency wave-forms into mechanical (acoustic) vibrations, thus producing thermal energy in the form of heat for penetration into tissues under treatment. Both the transducer crystal and the applicator cup are designed with the capability of providing at least three different output frequencies from a single applicator sound head, while supplying three different penetration depths for treating a patient's tissues.
