| Abstract: | The basic characteristics and electro-acoustic parameters of therapeutic transducer in frequency range from 200 kHz to 10 MHz are expounded.Their physical significances and relations are explained.The measure-ment methods of these parameters based on detecting the radiation force and the effective area are proposed.The measurement results of a plane piston transducer,a spherically focusing transducer and a cylindrically focusing transducer are given. |
| Keywords: | ultrasonic transducer therapeutic electro-acoustic characteristics measurement radiation force bal-ance effective area |
