LASER INDUCED CAVITATION IN BIOLOGICAL TISSUE

干涉测量方法已经被用来监测组织表面 纳米尺度在纳秒时间尺度内的运动。这已经是 用于研究激光消融的开始。结果是 发表在最近出版的一系列出版物中。改进后的 这项技术使得仔细监测激光诱导的空化成为可能。 水中的一种现象，时间分辨率为几纳秒。 这项技术也被应用于“软组织”(半月板)和 已有研究表明，空化发生在半月面内。这 目前正在使用一种技术来确定空化 水和盐水的阈值(抗拉强度)。

Interferometric methods have been used to monitor tissue surface movements of nanometer dimention in a nsec time scale. This has been used to study the onset of laser ablation. The results have been published in a series of publication published recently. The improved technique has allowed careful monitoring of laser-induced cavitation phenomenon in water with a temporal resolution of a few nanoseconds. This technique has also been applied to "soft" tissue (meniscus) and it has been shown that cavitation occurs within meniscus. This technique is currently being used to determine the cavitation threshold (tensile strength) of water and saline.
