Color Doppler ultrasound generally uses autocorrelation technology for Doppler signal processing, and the blood flow signal obtained by autocorrelation technology is processed by color

After encoding, it is 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 (that is, color Doppler ultrasound) not only has the advantages of two-dimensional ultrasound structure images, but also provides rich information about hemodynamics. Its practical application has received wide attention and welcome, and it is well-known in clinical practice. It is "non-traumatic angiography".
It is usually composed of probes (phased array, linear array, convex array, mechanical fan scan, three-dimensional probe, endoscopic probe, etc.), ultrasonic transmitting/receiving circuit, signal processing and image display. Using ultrasound Doppler technology and the principle of ultrasound echo, it is a device that collects blood flow movement, tissue movement information and human organ tissue imaging at the same time.
It is used for ultrasound imaging, measurement and blood flow movement information collection for clinical ultrasound diagnostic examination. The probe can be used in the esophagus, intravascular, intra-operative intra-human tissue, and/or used in ultrasound navigation and other fields.
