LASER INDUCED CAVITATION IN BIOLOGICAL TISSUE

干涉测量方法已被用于监测组织表面 在纳秒时间尺度内的纳米尺度的运动。 这是 用于研究激光消融的开始。 结果令人 在最近出版的一系列出版物中发表。 改进的 一项技术允许对激光诱发的空化现象进行仔细监测 这是一个在水中的现象，时间分辨率为几纳秒。 该技术也已应用于“软”组织（半月板）， 已经表明在弯月面内发生气穴现象。 这 技术目前被用来确定空化 水和盐水的阈值（拉伸强度）。

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.
