Development of portable acoustic output measurement system for medical ultrasonic diagnostic equipment / 医疗卫生装备

ABSTRACT

Objective To develop a portable acoustic output measurement system in order to satisfy the requirements of military itinerant inspection. Methods A hydrophone was used as energy converting equipment to collect wave of acoustic pressure in the field of ultrasound. Through some calculations using approximated formulas, a serious of acoustic output parameters were achieved. Results Main acoustic output parameters could be measured with permitted error. Conclusion This method is feasible, which can make up for the defects of current measurement.
