Patent ID: 8512250

Claim:
A medical ultrasound system comprising: a transducer assembly including a first focused ultrasound transducer configured to operate at a first frequency above 1 MHz and a second ultrasound transducer configured to operate at a second frequency below 1 MHz; a first signal generator coupled with the first focused ultrasound transducer, the first signal generator configured to cause the first focused ultrasound transducer to operate between 100-1000 watts with pulse durations less than 100 ms; and a second signal generator coupled with the second ultrasound transducer, the second signal generator driving said second ultrasound transducer in pulse mode, wherein the first focused ultrasound transducer and the second ultrasound transducer are configured to be simultaneously operated so the first focused ultrasound transducer creates bubbles by projecting ultrasound energy at the first frequency into adipose tissue and the second transducer causes the bubbles to collapse by projecting pulsed ultrasound energy at the second frequency into the adipose tissue.
