Characterization of ultrasound fields is a routine procedure for both diagnostic and therapeutic ultrasound. Quantitative field mapping with a calibrated hydrophone and multi-axis positioning system can be difficult and time consuming. In this study, the use of acoustic cavitation field mapping as a qualitative surrogate to acoustic pressure field mapping, albeit without acoustic pressure values is demonstrated. This technique allows for fast qualitative mapping of ultrasound fields and thereby functionality of the corresponding transducers, in a matter of seconds. In addition, this technique could be used to rapidly image in vivo acoustic cavitation fields during therapeutic ultrasound applications.
超声场的特性描述是诊断和治疗超声的常规程序。使用校准的水听器和多轴定位系统进行定量场测绘可能既困难又耗时。在这项研究中，展示了将声空化场测绘用作声压场测绘的定性替代方法，尽管没有声压值。该技术允许在几秒钟内快速定性地绘制超声场，从而可以快速检查相应换能器的功能。此外，该技术可用于在治疗性超声应用期间快速成像体内声空化场。
