The Doppler effect of sound waves can also be used for medical diagnosis, which is what we usually call color Doppler ultrasound. Color Doppler ultrasound simply means high-definition black and white B ultrasound plus color Doppler. First, let’s talk about the ultrasound frequency shift diagnosis method, namely D ultrasound. This method applies the principle of Doppler effect, when the sound source and receiver (ie When there is relative movement between the probe and the reflector, the frequency of the echo changes. This change in frequency is called frequency shift. D-ultrasound includes pulse Doppler, continuous Doppler and color Doppler blood flow images. . Color Doppler ultrasound generally uses autocorrelation technology for Doppler signal processing. The blood flow signal obtained by autocorrelation technology is color-coded and superimposed on a 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 on hemodynamics. Its practical application has received wide attention and welcome, and it is well-known in clinical practice. It is "non-traumatic angiography".
Introduction to Doppler Color Doppler Ultrasound Function
It is the most high-end color Doppler ultrasound in China and even in the world. In addition to the functions of ordinary color Doppler ultrasound, its unique excellent performance is mainly reflected in the following aspects:
Folding ultra-wideband frequency conversion probe and second harmonic imaging
It can increase the clarity of the image, expand the scope of the scan, and is suitable for patients of various weights.
Folding contrast-enhanced ultrasound probe and CnTI contrast-enhanced ultrasound technology
The combination of a unique probe and special imaging technology can significantly improve the differential diagnosis rate of benign and malignant lesions in the abdomen and superficial organs.
Folding VPAN wide-view imaging technology
The scope of scanning for superficial organs such as gynecological and obstetric diseases and thyroid glands has been expanded, and the early diagnosis of minimal lesions has been improved, and the detection rate of lesions with unclear boundaries and difficult to detect deep lesions has been increased.
Folding 3D imaging technology and diamond imaging
It can be used for systematic screening of fetuses, greatly improving the ultrasound detection rate of fetal malformations.
Folding 200° wide-angle female probe imaging
It provides more detailed information for the diagnosis of obstetrics and gynecology diseases, makes the image display clear, expands the scanning range, and significantly improves the diagnosis rate.
