Abstract (in Japanese) (See Japanese page) 
(in English) Establishment of fast and accurate measurement of ultrasound pressure field leads to the development of ultrasound application in medication. The most common method is a hydrophone scan which requires a long scanning time and disturbs the acoustic field. In this study, we used an optical phase contrast method for the measurement which enables a fast and noninterfering measurement. This method measures the modulated phase of light cause by the pulsed ultrasound pressure field. Then, we applied a CT algorithm to reconstruct the 3D ultrasound pressure field and measure the pressure field quantitatively. The result of optical phase contrast method was compared with that of hydrophone measurement and simulation and well agreement was achieved.
