What Is a Fetal Doppler Ultrasound?
The Doppler effect of sound waves can also be used for medical diagnosis, which is what we usually call color ultrasound. Color ultrasound is simply a high-resolution black-and-white B ultrasound plus color Doppler. First, let's talk about the ultrasonic frequency shift diagnostic method, that is, D ultrasound. This method uses the Doppler effect principle. When the sound source and receiver (ie When there is relative motion between the probe and the reflector, the frequency of the echo changes. This frequency change is called frequency shift. The D ultrasound includes pulse Doppler, continuous Doppler, and color Doppler blood flow images. . Color Doppler ultrasound generally uses auto-correlation technology for Doppler signal processing. The blood flow signals obtained by auto-correlation technology are 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 ultrasound) has the advantages of two-dimensional ultrasound structural images, and at the same time provides rich hemodynamic information. Practical applications have been widely valued and welcomed, and have been widely recognized in the clinic. "Non-traumatic angiography."
Doppler ultrasound
- Sonic
- It is the most high-end color ultrasound in China and even in the world. In addition to the functions of ordinary color ultrasound, its unique excellent performance is mainly reflected in the following aspects:
Doppler color Doppler ultra-wideband frequency conversion probe and second harmonic imaging
- It can increase the sharpness of the image, expand the scanning range, and is suitable for patients of various weights.
CnTI Doppler color Doppler ultrasound imaging probe and CnTI contrast ultrasound technology
- The combination of the unique probe and the special imaging technology can significantly improve the benign and malignant differential diagnosis rates of abdominal and superficial organ occupying lesions.
VPAN Doppler Color Doppler VPAN Wide Field Imaging Technology
- The scope of scanning for superficial organs such as gynecological and obstetric diseases and the thyroid gland has been expanded, the early diagnosis of small lesions has been increased, and the detection rate of unclear borders and deep difficult-to-detect lesions has been increased.
Doppler color ultrasound 3D imaging technology and diamond imaging
- It can be used for fetal system screening, which greatly improves the ultrasound detection rate of fetal malformations.
200° Doppler Color Doppler 200 ° Wide Angle Female Probe Imaging
- It provides more detailed information for the diagnosis of obstetrics and gynecology diseases, makes the image display clearer, expands the scanning range, and significantly improves the diagnosis rate.
