Performance Measurement of Ultrasonic Transducer for Surgery Application
Ultrasonic transducers are widely used in many fields including manufacture and medical. In order to transmit maximal ultrasonic power to an acoustic load in ultrasonic surgery system,measurement of ultrasonic transducer is of great importance. In this paper,performance of ultrasonic surgery transducers with different loads of water and pork bone,pork soft tissues like liver,muscle were measured by Dynamic Signal Analyzer and Network Analyzer. Mason equivalent circuit model was also used to confirm electroacoustic power when ultrasonic surgery transducer was in different loads and to assess the transducers performance. Results show that under small signals,the ultrasonic transducer has larger output power when contact bone than contact soft tissue or immerse into water.
