Abstract (in Japanese) (See Japanese page) 
(in English) High-intensity focused ultrasound (HIFU) is a noninvasive method for cancer treatment, in which ultrasound is focused to a target tissue for the coagulation. HIFU treatment efficiency improves by using cavitation bubbles which can be induced by a high-intensity ultrasound pulse. However, cavitation bubbles may cause side effects such as skin burn when they are generated outside the target region. One of the cause is considered to be the effect of standing waves generated between the coupler water and the reflective surface of the body surface. In this study, a method to reduce standing wave components using a six divided transducer was developed, and the advantage of the proposed method was experimentally investigated.
