The Super-Tech 4D Sonogram Video Description: Get to know your baby in a whole new dimension! A four dimension ultrasound, or 4D sonogram, is a pregnancy test that's like a live video starring your baby-to-be! The 4-D sonogram is also an effective way to screen for certain kinds of birth defect.
Transcript: You may already be familiar with the sonogram pictures your doctor takes of your baby. Now, modern technology is taking the sonogram to a whole new dimension. A normal sonogram uses a probe to transmit sound waves into your belly. The probe then “listens” for an echoing sound, which it uses to create a three dimensional picture of your fetus. Recently, doctors have discovered an even more advanced viewing technology: The four dimensional sonogram.  A 4D sonogram works in the same way as a 3D one, but adds a fourth-dimension—time—to the picture. The result is a live-action “video” of your baby in real time. With a 4D sonogram, you can watch your baby wriggle, smile, suck his thumb, and more. Doctors like 4D technology, too, because the movement patterns can help a doctor quickly discern how a baby is developing. The 4D sonogram is also a valuable diagnostic tool because it can identify problems with a fetus sooner than would otherwise be possible.  After a 4D sonogram, your doctor can use a process called volume rendering to take moving images and compile them into still-frame photos. Because 4D sonograms are still relatively new, they are not available in all hospitals – nor are they necessary for most pregnancies.  If you’re interested in learning more about this viewing technology, talk to your doctor.
