What is 3D/4D color Doppler ultrasound?

3D color Doppler ultrasound is a kind of color Doppler ultrasound, and 3D color Doppler ultrasound is a three-dimensional dynamic display. The advantages of 3D color ultrasound are mainly in the following fields
① The sensitivity and display rate of uterine artery and ovarian blood flow are high.
② Shorten the inspection time and obtain accurate Doppler spectrum.
③ No need to fill the bladder.
④Do not interfere with body type obesity, abdominal scars, and intestinal inflation.
⑤ Find the tender part of pelvic organs by means of the movement of the probe tip to determine whether there is adhesion in the pelvis.
3D color ultrasound surface imaging is used in obstetric examinations, not only to observe the process of fetal growth, but also to examine changes in the placenta, amniotic fluid and umbilical cord, and more importantly, it can be used as the main means to diagnose fetal malformations. Due to the large contrast between the tissue structure and the liquid gray level, it can clearly display the three-dimensional shape, surface features and spatial position relationship of the suspicious structure, and provide a three-dimensional image of the fetus in the womb. 3D reconstruction includes surface imaging, transparent imaging and multi-plane imaging modes.
3D Color Doppler Features
(1) Adding coronal section images on the basis of retaining 2D imaging.
(2) Stereotaxic, axis adjustment, three axis planes of ABC can be adjusted at will until the best image is displayed.
(3) Stereoscopic imaging, dynamic and intuitive; real-time dynamic observation of fetal head, body surface and internal organs activities, the image is clear, accurate and reliable.
(4) The cutting function can keep the key points of the image; cut off the useless parts, and perform 3D reconstruction and display on the suspicious parts.
(5) Rotation function, which can be observed from multiple sides; with 360° rotation function of front and rear, left and right, and up and down, the image can be comprehensively observed in different directions.
(6) It can take beautiful photos of the fetus, record the expression changes and burn the disc as data preservation, and keep it as a permanent memory.
(7) The three-dimensional relationship and adjacent relationship of lesions at different levels can be displayed. The application of 3D color ultrasound in obstetrics provides a wealth of image information for clinical ultrasound diagnosis. The fetus is surrounded by liquid in the amniotic cavity, which is a good imaging condition for 3D ultrasound. The image is three-dimensional and intuitive, and the angle can be adjusted arbitrarily. The suspicious structure can be observed by rotation, and the deformity of the general structure of the fetus can be seen at a glance, which greatly improves the quality of diagnosis and treatment and reduces misdiagnosis or missed diagnosis.
3D color Doppler time
Generally 22 to 26 weeks of pregnancy to do three-dimensional color Doppler ultrasound to check the development of the fetus to rule out deformities, is an ideal time.
Four-dimensional ultrasound
Four-dimensional color ultrasound diagnostic apparatus is the world’s most advanced color ultrasound equipment. “4D” is the abbreviation of “four-dimensional”. The fourth dimension refers to the vector time. For Ultrasound, 4D Ultrasound technology is a newly developed technology and an exclusive technology of the Canadian company Yusheng. 4D ultrasound technology uses 3D ultrasound images plus time dimension parameters. This revolutionary technology can acquire 3D images in real time, surpassing the limitations of traditional ultrasound. It offers a wide range of applications including abdominal, vascular, small organ, obstetrics, gynecology, urology, neonatal and pediatrics. The result: the ability to display real-time moving images of your unborn baby, or real-time moving images of other human internal organs.
Compared with other 3D ultrasound diagnostic procedures, 4D ultrasound allows doctors to observe the dynamic movements of the internal organs of the human body in real time. For example, doctors can judge the development of the fetus according to the movement of the fetus, and the accuracy of puncture under ultrasound guidance can be improved by observing the three-dimensional plane movement of the puncture needle. So clinicians and sonographers can detect and find a variety of abnormalities.
4D Color Doppler Ultrasound is a complete ultrasound system for breast imaging, interventional urology, and general medical imaging. As a complete set of ultrasound equipment, it can be used to conduct the following studies:
◆Determination of fetal age
◆Analyze fetal development
◆Evaluation of multiple births and/or high-risk pregnancies
◆Detect fetal abnormalities
◆Detect structural abnormalities of the uterus
◆Detect placental abnormalities
◆Detect abnormal bleeding
◆Detect ectopic pregnancy and other abnormal pregnancy
◆Detect ovarian tumors and fibroids
◆Location of the placenta
With high-definition image quality, the “four-dimensional cinema” four-dimensional color ultrasound diagnostic instrument for expectant mothers can automatically take intrauterine “photographs” and dynamic videos for the fetus, adding peace of mind and interest to many expectant mothers.
They no longer just feel the baby’s breathing and movement, but can witness their every move and well-behaved looks. More importantly, the four-dimensional color Doppler ultrasound can observe the growth and development of the fetus in the uterus from multiple directions and angles, and provide an accurate scientific basis for the early diagnosis of fetal congenital body surface deformities and congenital heart diseases. In the past, B-ultrasound equipment can only check the physiological indicators of the fetus, while the 4D color ultrasound can also check the body surface of the fetus, such as cleft lip, spina bifida, brain, kidney, heart, skeletal dysplasia, etc. Treat as soon as possible. It is no longer a fantasy to have a smart and healthy baby, and make the baby’s appearance and actions into photos or VCDs, so that the baby has the most complete 0-year-old photo album.
In addition, the excellent ergonomic design of the four-dimensional color ultrasonic diagnostic instrument does not exist in radiation, light waves and electromagnetic waves, and has no impact on human health.
