| Research Abstract |
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.
