摘　　要：连续波超声多普勒成像可以测量高速血流,作为高速血流定量分析的一种重要手段,是中高端彩超的一项关键功能。由于成本等原因,在低端彩超和黑白超上少有配备,本文提出一种低成本的连续波超声多普勒电路方案,降低使用条件,丰富低端彩超和黑白超的功能。Continuous wave Doppler echocardiography can measure the speed of blood lfow, as an important method for quantitative analysis of high-speed lfow, which is a key feature of high-end color Doppler ultrasound. Due to the cost and other factors, few B/W ultrasound and low-end color Doppler ultrasound systems are conifgured with such feature. A low cost circuit design of continuous wave Doppler ultrasound is described in this paper. Such design has lower use conditions, but adds up new functions in B/W ultrasound and low-end color Doppler ultrasound.
