Development of a novel method to enhance localized heating by cavitation bubbles for ultrasound cancer treatment

高强度聚焦超声（HIFU）治疗作为一种无创的癌症治疗方式正受到人们的关注。但存在治疗时间长等问题。在HIFU的焦点区域产生的声空化可以增强组织加热。在本研究中，通过观察空化气泡的行为，探测和研究来自气泡的分散压力波来进行空化监测。对光学测压方法进行了研究。

High-intensity focused ultrasound (HIFU)therapy is attracting attention as a noninvasive therapeutic modality for cancer. However, it has a problem of long treatment time. It is known that acoustic cavitation generated in the focal region of HIFU enhances tissue heating. In this study, the behavior of cavitation bubbles were observed and scattered pressure waves from the bubbles were detected and investigated for the cavitation monitoring. The optical pressure measurement method was also investigated.
