Abstract
A design of a low-cost bipolar pulse generator for high-frequency (HF) ultrasound applications is presented. The pulse generator can produce N cycle (1-255 cycles) bipolar pulses with center frequency over 60 MHz. The measured pulse amplitude was over 160 Vpp, and the pulse ringing was less than 0.3 Vpp (i.e., signal-to-ring ratio is 55 dB). The pulser can be used in high-frequency ultrasound Doppler and B-mode imaging applications with arrays.
摘要
本文提出了一种用于高频（HF）超声应用的低成本双极脉冲发生器的设计。该脉冲发生器可以产生N个周期（1 - 255个周期）的双极脉冲，中心频率超过60 MHz。测量得到的脉冲幅度超过160 Vpp，脉冲振铃小于0.3 Vpp（即，信环比为55 dB）。该脉冲发生器可用于带阵列的高频超声多普勒和B模式成像应用。
