Abstract :
To meet the requirement for more efficient and convenient method of high-intensity focused ultrasound (HIFU for short) sound field measurement, which is propelled by the development of HIFU therapy, this paper theoretically discusses the feasibility to measure the focal region sound intensity of HIFU transducer by hydrophone method that uses narrow modulated wave as inspiring signal. It is proved through experiments to be a quick, efficient, safe and reliable method for the measurement of HIFU sound intensity.
