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。
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.
