| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | High-intensity focused ultrasound (HIFU) is a noninvasive method for cancer treatments, in which ultrasound is focused to a target tissue for the coagulation. Cavitation bubbles can be used to increase the HIFU treatment efficiency. However, cavitation bubbles may cause side effects such as skin burn when they are generated outside the target region. The effects of standing wave components caused by the reflection at the tissue boundaries such as skin is considered to be one of the causes to generate the unwanted cavitation babbles. In this study, a method to reduce standing wave components using array transducer was developed, and the advantage of the proposed method was experimentally investigated. | |
