Abstract:
Objective To study the measuring method for amplitude of transducer's tip in ultrasonic surgical apparatus, and design a set of practical detecting system with special data processing technique. Methods The system was consisted of stereomicroscope, CCD camera, etc. The images of amplitude measuring were captured and processed and the result was carried out at last. Results The measurement range for amplitude of transducer’s tip was above 190 ?m, the precision was below 10?m, and the repeatability was also ideal. Conclusion The amplitude measuring method has some excellent characters such as directness, simplicity, easy implementation, error estimableness and controllability, etc. It is proved in practice that the effect is nice and the blank in this field in China is filled.
