Abstract :
Nowadays, ultrasound medical imaging is more and more demanding with respect to transducer performance evaluation and optimization. Conventional tools and setups are limited in the complete evaluation and characterization of ultrasound imaging transducer, for example in the analysis of cross coupling (radiating and nonradiating). A vibration measurement method for ultrasonic array transducer using laser interferometry is presented. This method allows array designers to perfectly characterize the acoustic transducer, and contributes to the advanced optimization of bandwidth, cross coupling and sensitivity of ultrasound imaging array transducers
