Currently, unmet clinical needs of nonsurgical high-intensity focused ultrasound (HIFU) fat reduction are a long time to see the fat reduction after HIFU lipolysis, long treatment time,low treatment efficacy. The porcine study has corroborated that the ultrasonic fast-shaping system can generate a strip-shape focal zone to form a line-shape hot spot, shortening treatment timeincreasing the amounts of lysed adipocytes,combine with the passive exercise to accelerate metabolism of the free lipids from necrotic adipocytes, improving the reduction in the waist circumferences.
