Abstract
The electro-acoustic radiation conductance is a quantitative parameter which characterizes the ability of transforming electric energy to acoustic energy on the ultrasonic transducer. To evaluate the performance of medical ultrasonic probe, we designed an electro-acoustic radiation conductance measurement system based on the radiation force balance method and the switching circuit unit for driving each element of array probe. The measurement results suggest that the developed system can be used reliably for the performance evaluation of medical ultrasonic array probes.
