In words:

What are 3D and 4D Ultrasounds?

3-D ultrasound can provide a static, three-dimensional images of what is scanned. The transducer records data of the area and the computer processes these images and presents them as an image that takes on a more life-like appearance.

Besides the visual difference, volumetric measurements are often more accurate and certain abnormalities or the absence of a certain abnormality can often be obtained.

More recently, 4-D or dynamic 3-D scanners are being used. These computers have the ability to record process the data so the 3-D images can be seen in motion. 4-D ultrasounds can present the movements of a baby before birth.

Most experts at his point do not consider 3-D and 4-D ultrasounds will become a quick replacement over conventional 2-D scans. Right now they act as an additional tool, much like doppler. Most diagnosis is still being made with 2-D scans.
