4D sonogram is also called the real time 3D ultrasound. It captures the image of a fetus as it moves. This gives a wide variety of opportunities to physicians for determining the health of the fetus, with much higher accuracy. Besides, it causes minimal trauma for both mother and the baby, compared with other types of examinations.

The basic operating principle of the three dimensional ultrasound is to create a large number of two dimensional images. All these images are made from different angles. When they are put together, it is possible to see the image in all three dimensions. This way the physician is able to see different two dimensional plates in rotations.

When you add an additional dimension, the time, you get the 4D sonogram. Thanks to sophisticated and improved technology, the image now can be seen in a real time, without characteristic delay. It means you can see the fetus as it moves, from different angles. This is a significant improvement when it comes to diagnostic evaluations.

Thanks to a very clear image displayed in a real time, a fetal age, health condition and other characteristics are clearly visible to the experienced physician. Different health issues, including problems related to fetal or placental abnormalities or some other similar issues are easier to notice. This makes this technology highly beneficial.

Physicians can detect different structural problems with uterus or recognize high risk pregnancies with more accuracy, and earlier that it was possible using other technologies. In some cases, early diagnostic is very important. The person that performs this scanning have to be highly educated for this job, to be able to recognize such abnormalities and to diagnose the actual problem.

The best period for making very clear and detailed images of a fetus is the one between the twenty sixth and thirty second week.The fetus is now perfectly formed and usually active, and videos made in this period can be really something special. After that, a fetus usually change its position, and it takes longer time to make a good video. Many people love the idea of making the video, but it has to be made properly.

Although it can be extremely useful in early diagnostics, some physicians use this technology for some other purposes. One example is so called keepsake ultrasound. It is performed just to give a chance to a woman to see her unborn child. It could have positive effects on both expecting parents, because it may increase bonding. It is generally advised not to perform this type of scanning under 17 weeks.

If you would like to determine the sex of the fetus, it is good to know that that cannot be done with high accuracy until the fetus is at least sixteen weeks old. Although some facilities perform this type of scanning earlier, the accuracy at earlier gestational age is questionable. Medical centers mostly advise it before 20 weeks, unless there is a medical reason for it.

There were several studies about the impact of this scanning of fetal development. No harmful effects were noticed, but you should still be aware of this possibility. This procedure does rise temperature and creates sort of mechanical vibrations. If the procedure lasts too long, in order of getting clearer and more interesting video, it might have some consequences. Make sure to use 4D sonogram and other helpful technologies wisely.
