US Patent 8454540 Non-invasive ultrasonic body contouring

An apparatus for lysing adipose tissue, the apparatus comprising a power source and a modulator assembly configured to supply modulated electrical power; an ultrasonic therapeutic transducer connected to the power source and modulator assembly and configured to convert the modulated electrical power to ultrasonic energy directed at a target volume in a region of a body containing adipose and non-adipose tissue, so as to selective generally lyse the adipose tissue and generally not lyse the non-adipose tissues; an ultrasonic imaging sub-system configured to identify changes in the target volume resulting from the ultrasonic energy; and a lipolysis control computer configured to control the power source and modulator assembly based on the changes identified by the ultrasonic imaging sub-system.
