Prenatal ultrasound
-
Sound waves are generated and directed toward the fetus and is a safe procedure in the hands of a qualified obstetrician. The picture is formed when sound waves are reflected back from the fetus. In 2D ultrasound, sound waves are directed straight down into the fetus then back up again. The image reflected back is only two-dimensional, which means there is no depth or perspective associated with the image, just a flat look.
3D ultrasound uses a process known as "surface rendering," which allows sound waves to be sent toward the fetus from more than one direction. Sophisticated software then interprets the images to compose an image of the fetus that shows more depth and enhances its features so the parents get to experience a more realistic image of their growing child.
Bonding
-
3D ultrasound offers a positive experience for both parents. Good prenatal care is reinforced with the mother, and a bonding experience between both parents and their child occurs with the utilization of this process. Following a 3D ultrasound visit, expectant mothers will often show a marked increase in improving their diets, eliminating the urge for drinking and smoking during pregnancy and maintaining a good exercise regimen.

Precautions
-
3D ultrasound is an elective process, which means it isn't part of the ultrasound prescribed by an obstetrician. Typically obstetricians prefer to limit the fetus's exposure to ultrasound in order to minimize risk to the fetus. While using 3D ultrasound is a safe procedure, it is wise to discuss the additional exposure with an obstetrician and use it in conjunction with regular prenatal 2D ultrasound.
Ultrasound providers
-
There are certain aesthetic benefits from a 3D ultrasound. Parents often enjoy showing the images of their growing child to friends and family, and the pictures or videos are a popular keepsake. It is important to choose a provider who makes safety and professionalism the main priority. A good 3D ultrasound provider will want proof that the mother is already receiving prenatal care from a qualified health care professional. The mother should also have proof of a complete, full anatomical ultrasound study in the second trimester of pregnancy. Actual 3D ultrasound scan time should be limited to no more than 25 minutes per session, with all findings being reported to the mother's obstetrician.
