Abstract (in Japanese) (See Japanese page) 
(in English) High-intensity focused ultrasound (HIFU) is a noninvasive method for cancer treatments, and one of the requirements for clinical use is to make the treatment more efficient. One of the approach, there is a multi-channel array transducer to enlarge treatment volume by making multiple focal points and scanning focal points. Since array transducer needs driving circuits for each channel, we have developed studying compact and high-efficiency driving circuits. In this study, we designed and made a driving circuit for array transducers considering the impedance properties. We compared new circuit and prior circuit by simulating its electrical power consumption and measuring focal pressure.
