| Abstract: | Ordinary the Doppler effect in blood flow was explained with the variation of period or wavelenth. From vector compositing, the Doppler effect in blood flow is now explained with the variation of propergation velocity of ultrasound in different coordinates. The basic formula of Doppler frequency shift is derived. The experimental results are discussed. |
