ABSTRACT
A data processing method for the sound power of the medical ultrasonic diagnostic equipment is introduced in this paper. The sound power for the transducer of a medical ultrasonic diagnostic equipment is measured for many times, and then the mathematical model based on the measurement data above is processed with Kalman filter.The output fluctuations for sound power of the equipment and its transducer as well as the measurement errors of sound power meter are eliminated to achieve the true value of sound power. Compared with other mean methods, the method above can improve the dicreteness of the measurements, and thus is worth being applied to processing other measured data.
