What is the difference between 3D ultrasound and 2D B ultrasound and ordinary B ultrasound?

Three-dimensional real-time color ultrasound not only has all the functions of two-dimensional color ultrasound, but also has its special functions of stereoscopic imaging, image cutting, image rotation and high-plane image analysis. Dynamic 3D technology can be used to observe the activity and morphology of the fetus in the uterine cavity, which can detect infant malformations early. Three-dimensional color ultrasound realizes the stereoscopic imaging of local tissues and organs of the human body, which can be used for volumetric scanning of abdomen and small organs, and accurately measure local tissues and organs, such as by examining the neck and back of the fetus ** and measuring the thickness of subcutaneous tissues, hereditary (chromosomal) malformations can be found during 9-13 weeks of pregnancy.

The outstanding feature of three-dimensional color ultrasound is that it can take local stereoscopic images of the growth and development of fetuses in utero at different gestational weeks, and the left ear and small fist of the sleeping fetus in the uterus and the vivid and vivid facial expressions can be clearly seen from the three-dimensional picture.

The big difference is that 4D ultrasound technology uses 3D ultrasound images plus time-dimensional parameters, and this revolutionary technology can obtain 3D images in real time, surpassing the limitations of traditional ultrasound. It offers a wide range of applications in a wide range of fields, including abdomen, vascular, small organ, obstetric, **, urology, neonatal and pediatrics.

Doing B ultrasound is a medical technology in our country, which is very popular and very easy to use, and has an important position in a number of medical technology methods, and is also chosen by many people. So in the B ultrasound, there is also the difference between ordinary B ultrasound and three-dimensional B ultrasound, and the next thing I want to explain to you is that there are some differences between ordinary B ultrasound and three-dimensional B ultrasound, you can take a look.

So when it comes to this three-dimensional B-ultrasound, many people may be curious, because in the routine pregnancy test, isn't there already a one, blind B-ultrasound examination? So what I want to explain to you here is that this three-dimensional B ultrasound is a kind of color ultrasound, so there are some differences with ordinary B ultrasound, so the function of three-dimensional B ultrasound, including all the functions of ordinary B ultrasound, in addition, it also has a lot of its own advantages, for example, there is a three-dimensional imaging function, which can rotate and cut the image, and can analyze the image of a high plane, so by doing a three-dimensional B ultrasound examination, we can have a clearer understanding of the growth of the baby in the belly. Congenital fetal diseases such as cleft lips can also be detected as early as possible. There are still many advantages of three-dimensional B ultrasound, which can distinguish benign and malignant tumors, observe non-jujube stuffiness, and observe pelvic varices through the bloodflow spectrum and so on.

So by reading the above, we can have a simple and basic understanding of some differences between ordinary B-ultrasound and three-dimensional B-ultrasound. Then ordinary B-ultrasound is chosen by many people and has some relatively basic detection effects. Compared with ordinary B-ultrasound, the three-dimensional ultrasound is more three-dimensional, so it is chosen by more pregnant women.

1. Three-dimensional color ultrasound is a three-dimensional static **, while four-dimensional color ultrasound is a three-dimensional dynamic**.

2. In addition, three-dimensional color ultrasound is relatively cheaper, and four-dimensional color ultrasound is more expensive, four-dimensional color ultrasound can see a series of actions of the child in the womb, but three-dimensional color ultrasound cannot, but whether it is three-dimensional or four-dimensional, it can be checked frequently, because there is a certain amount of radiation to the child.

3. If pregnant women do a large deformity examination after 20 weeks, the first choice should be system B ultrasound, system B ultrasound is safer for children, only through two-dimensional color ultrasound can rule out the deformities of the child's various systems, but this kind of color ultrasound must go to the local qualified hospital to check and block, because the technical requirements for doctors are relatively high.

B-ultrasound is divided into two-dimensional, three-dimensional and four-dimensional color ultrasound: two-dimensional color ultrasound is a flat image, three-dimensional color ultrasound is a three-dimensional static image, and four-dimensional color ultrasound is a three-dimensional dynamic image.

Two-dimensional" color ultrasound.

In traditional ultrasound deformity, the image shows a flat image of an organ or structure, which can preliminarily determine whether the fetus has a malformation.

Three-dimensional "color ultrasound."

On the basis of "two-dimensional", the fetal surface imaging function is added to present three-dimensional images and judge some obvious appearance malformations of the fetus.

Advantages: It can only show all aspects of the human organ, and the fetus is deformed from the inside out.

Four-dimensional" color ultrasound.

On the basis of "two-dimensional" and "three-dimensional", dynamic stereoscopic images are presented to increase fetal dynamic observation.

Advantages: ultrasound examination of the fetus can show the color, face and development of various organs of the fetus in three dimensions; Body structure deformity is eliminated from multiple angles and directions of the fetus.

Hello, when you are 22-26 weeks pregnant, you can come to do a four-dimensional color ultrasound prenatal deformity, four-dimensional color ultrasound can show the color, face, and development of various organs of the fetus in three dimensions, and even the state of the fetus in the mother's body can also be observed; It can be early diagnosis of fetal malformations, such as cleft lip, cleft palate, abnormal bone development, cardiovascular malformations, etc. Understand the intrauterine dynamics of the fetus, and then dynamically record the intrauterine status of the fetus for permanent memorial. Ordinary two-dimensional color ultrasound examination is not as clear and accurate as four-dimensional color ultrasound, which is used throughout pregnancy.

Yes, but if you do a deformity test, it may not be as good as the suburban fruit done at 22-26 weeks.

B-ultrasound is a black-and-white ultrasound diagnostic technology, and the image measured by the ultrasound probe is black and white, and can only observe the tissue structure of the fetus, how big the measuring head is, and how long the body is. Color ultrasound can observe the blood flow of the fetus, which is conducive to timely detection of fetal abnormalities, such as if there is a blood flow ring in the neck of the fetus, it means that the umbilical cord around the neck can lead to suffocation death.

Ordinary 2D color ultrasound examination is not as clear and accurate as 4D compared with 4D. Four-dimensional color ultrasound provides multi-faceted applications in many fields, including abdomen, blood vessels, small organs, obstetrics, urology, neonatology, and pediatrics. The result is:

It can display a real-time dynamic image of your unborn baby, or a real-time living image of other internal organs.

Compared with other ultrasound diagnostic procedures, the dynamic movement of the internal organs of the human body can be observed in real time. Clinicians and sonographers can detect and detect a wide range of abnormalities, from vascular malformations to inherited syndromes. Four-dimensional color ultrasound can observe the growth and development of the fetus in utero from multiple directions and angles, and provide an accurate scientific basis for the early diagnosis of congenital body surface malformations and congenital heart diseases of the fetus.

In the past, the ultrasound equipment could only check the physiological indicators of the fetus, while the four-dimensional color ultrasound can also examine the body surface of the fetus, such as cleft lip, spina bifida, brain, kidney, heart, bone dysplasia, etc., so as to be carried out as soon as possible**. It is no longer a fantasy to give birth to a smart and healthy baby, and make the baby's appearance and actions into ** or VCD, so that the baby has the most complete 0-year-old photo album.

In addition, the excellent ergonomic design of the four-dimensional color ultrasound diagnostic instrument does not have any radiation such as rays, light waves and electromagnetic waves, and has no impact on human health.

The difference between three-dimensional color ultrasound and four-dimensional color ultrasound is a time dimension, and the popular understanding is that three-dimensional color ultrasound is **, and four-dimensional color ultrasound is video. Three-dimensional color ultrasound can observe the process of fetal growth, check the changes of placenta, amniotic fluid, and umbilical cord, and can detect fetal malformations. Four-dimensional color ultrasound is currently the most advanced ultrasound equipment in the world, which can display the real-time dynamic image of the baby, so that the expectant mother can see the baby's every move in the womb through the screen, and observe the baby's voice and smile.

The diagnosis of fetal malformations by four-dimensional color ultrasound is more comprehensive and accurate than that of three-dimensional color ultrasound, because four-dimensional color ultrasound is a dynamic observation, and three-dimensional color ultrasound is a static observation, so the three-dimensional effect of four-dimensional color ultrasound is better than that of three-dimensional, and the observation is more detailed and comprehensive. Of course, ** is a little more expensive than 3D color ultrasound.

Four-dimensional color ultrasound and three-dimensional color ultrasound are actually similar in principle, but four-dimensional color ultrasound is three-dimensional imaging, which can be burned into a disc for permanent storage, which can be more clear and dynamically observe the development of the fetus.

In fact, three-dimensional and four-dimensional color ultrasound are observed with ordinary color ultrasound, and then the observed plane image is converted into three-dimensional and four-dimensional three-dimensional images through the conversion software in the instrument.

The difference between three-dimensional and four-dimensional is in one"Time dimension", that is, three-dimensional color ultrasound is **, and four-dimensional color ultrasound is a video, which can allow pregnant mothers to see a series of movements of the fetus.

Four-dimensional color ultrasound is more comprehensive than three-dimensional color ultrasound, more three-dimensional, three-dimensional color ultrasound is only the first at a certain point in time, and four-dimensional color ultrasound is a dynamic image, which can be burned into a disc.

Four-dimensional color ultrasound has one more time dynamic axis than three-dimensional, and there are not only ** but also dynamic videos for shooting four-dimensional. I heard from Jerry's 4D doctor when I was filming before. Images and ** can record the growth process of the fetus.
