Current acoustic techniques for studying cavitation dynamics are only readily applicable to single-bubble activity, while optical methods can only be used in transparent media. However, multi-bubble cavitation often occurs in opaque media such as biological tissue. Here, the signals received passively by each of the 64 channels of a diagnostic ultrasound array are used to localize and separate emissions from several bubble clusters cavitating in agar gel, thereby providing a method of observing cavitation dynamics. The method has a high spatiotemporal resolution and is applicable to cavitation in opaque media.
目前用于研究空化动力学的声学技术仅适用于单泡活动，而光学方法只能用于透明介质。然而，多泡空化经常发生在不透明介质中，如生物组织。在这里，利用诊断超声阵列的 64 个通道中的每一个通道被动接收的信号，对在琼脂凝胶中空化的几个气泡簇的发射进行定位和分离，从而提供了一种观察空化动力学的方法。该方法具有较高的时空分辨率，适用于不透明介质中的空化。
