The Clinical Applications of Multifrequency Ultrasound Technology in Body Reshaping

The basic rules of UAL as described by Zocchi were followed without regard to other limitations such as ultrasonic energy site times, body areas, and level of tissue planes. US alters adipose tissue through micromechanical disruption and cavitation with minimal thermal effect. The cavitational effect is a dynamic phenomenon, triggered by the accomplishment of resonance frequency of cell membrane. Resonance frequency is dependent on the kind of tissue and surrounding environment characteristics that usually change continually during treatment. To use the better frequency in all conditions and to maintain the maximum effectiveness, the MAUL technology was introduced. This new technology uses last-generation microchips to determine the best resonance frequency every 10 s by measuring tissue humidity and impedance. By maintaining the better frequency during treatment, the new technology concentrates the entire ultrasound energy on the adipose cells minimizing the thermal effect on the cutaneous deeper layer and maximizing the lipoclastic effect.
