The system comprises a therapeutic bed, a chamber, a combined head, a motional apparatus, a therapeutic power source, an imaging power source, a vacuum degassor, and a controller. The therapeutic transducer, the imaging transducer, and a rotator, together form the combined head. The combined head may also include an actuator. The rotator and actuator move the imaging transducer relative to the therapeutic transducer. The therapeutic transducer produces high intensity focused ultrasound, and treats target tissue in the body.
