Ultrasound pulsed transducers are very important for blood flow measurement and imaging. Ultrasound pulsed transducers are broadband transducers which require relatively heavy external damping to achieve a good axial resolution and an adequately wide bandwidth. In this work, using a simple RLC circuit model, broadband transducers were constructed and tested. The results are quite applicable for pulsed Doppler blood flow measurements.
超声脉冲换能器对于血流测量和成像非常重要。超声脉冲换能器是宽带换能器,需要相对较重的外部阻尼才能实现良好的轴向分辨率和足够宽的带宽。在这项工作中,使用简单的RLC电路模型构建并测试了宽带换能器。结果非常适用于脉冲多普勒血流测量。
