TECHNIQUE AND APPARATUS FOR ULTRASOUND THERAPY

摘要

The present invention is directed to an imaging compatible device which employs ultrasound energy for thermal therapy. Directionality of the thermal therapy is effected through transducer structure and rotational control of the device. The depth of thermal therapy can also be controlled through simultaneous modulation of the device's operating frequencies and ultrasonic power. The device comprises at least one transducer, in combination with at least one acoustic coupling layer, adapted to provide mutlifrequency operation, and located within a housing suitable for tissue insertion. The invention also provides methods of using the device for providing thermal therapy or for activating an/or enhancing the delivery of therapeutic agents.
