摘要：

Transmission line lengths in the protection circuitry of a high frequency (> 20 MHz) ultrasound imaging system, have an important effect on the frequency, amplitude and bandwidth of the pulseecho response of the system. A model that includes the transmission line lengths between the pulser, transducer and receiver, and the electromechanical properties of high frequency transducers, is used to illustrate the importance of correctly choosing these line lengths. An iterative optimization procedure for designing the protection circuitry for a broad band system is proposed. A theoretical and experimental analysis of the validity of this approach is reported for a 45-MHz PVDF transducer.
