非侵入式超声塑形及其实现的关键技术

Key techniques of the body contouring by non-invasive focused ultrasound

摘要: 非侵入式超声塑形是最近几年刚刚兴起的技术,使用特殊的换能器产生高能量聚焦超声波作用于人体脂肪层,利用超声波的空化效应破坏脂肪细胞膜,游离的脂肪通过人体代谢系统排除体外,从而达到塑形的目的。此项技术具有安全无创等优点。简要讨论了非侵入式超声塑形的物理机理、工作参数、实际系统的构成和工作原理,重点介绍了其中的两项关键技术:超声塑形系统中的发射换能器和频率跟踪技术的应用。

Abstract: In recent years,the technology of focused ultrasound is used for body contouring with the advantages of non-invasive and safe.The principles of body contouring by focused ultrasound,system composing and working parameters are briefly introduced.Specifically,two key techniques,the ultrasound transducer and frequency tracking are discussed.
