Abstract:
Ultrasonic therapy technology is a research hotspot in the field of biomedicine,and the quality control and regulatory requirements for the ultrasonic physiotherapy equipment are also increasing.Based on this,the working principle and structure of ultrasonic physiotherapy equipment were analyzed,and a calibration method of ultrasonic physiotherapy equipment was proposed from the aspects of ultrasonic output power,effective radiation area and acoustic working frequency,etc.,aiming at its main measurement parameters,so as to provide technical reference for its measurement performance evaluation.Two ultrasonic physiotherapy equipment produced by different manufacturers were selected and tested to analyze the calibration results.The results showed that the calibration results were scientific and reasonable,highly operational,and in line with national standards,which can provide technical reference for metrology technical institutions to carry out related work.
