Abstract
This invention discloses an equipment for lipolysis of fat of a living body by ultrasound sonication. An effective ultrasound is characterized in low frequency 15-140 kHz region, by an intensity when in a range of 15-50 kHz, which is greater than 10 mw/cm2and below a hemolysis limit, and an intensity when in a range of 50-140 kHz, which is greater than 4 mW/cm2 and below the hemolysis limit or the safety level defined by MI. The invention is further characterized in a high frequency 180-1.3 MHz region, by an intensity when in a range of 180-700 kHz, which is greater than 10 mw/cm2 and below the safety level defined by M.I, and the intensity when in a range of 700 kHz-1.3 MHz, which is greater than 800 mw/cm2and below the safety level defined by MI.
