Color Doppler ultrasound ultrasound

Color Doppler ultrasound generally uses autocorrelation technology for Doppler signal processing, and the blood flow signal obtained by autocorrelation technology is color coded and superimposed on the two-dimensional image in real time to form a color Doppler ultrasound blood flow image. It can be seen that color Doppler ultrasound (color Doppler ultrasound) not only has the advantages of two-dimensional ultrasound structure images, but also provides rich information on hemodynamics. The practical application has been widely valued and welcomed. It is known as "non-traumatic angiography" in clinical practice ".
The related technology used by color Doppler ultrasound is pulse wave. When the speed of the detection object is too high, the color of the color flow will be wrong, which is obviously inferior to spectral Doppler in quantitative analysis. Nowadays, color Doppler ultrasound has the function of spectral Doppler, that is, color-dual-function ultrasound.
