The increasing availability of 3D ultrasound has resulted largely from the brisk advancement in computer technology. The aim of three-dimensional imaging is to eliminate invasive tests whenever possible and simplify workflow.

3D ultrasound scans are as safe as traditional ultrasound scanning because the image is composed of sections of two-dimensional images, so the ultrasound exposure is the same. In this procedure, several two-dimensional images are combined by specialized computer software to form three-dimensional images.

With three-dimensional imaging, sonologists can get the full picture in a single image. They can see the entire brain in one view instead of multiple images. Achieving comparable results with a routine 2D scan of the head requires at least three separate scans. In other scenarios, such as abdominal scans, it is not possible to obtain a third view with a routine scan. Three-dimensional imaging allows a physician to get a better look at the organ being examined and is best used for early detection of tumors, discovering masses in the colon and rectum, detecting breast lesions for possible biopsies, assessing the development of a fetus, and visualizing blood flow in various organs. Three-dimensional scans greatly aid in the diagnosis of problems by showing more detail from different angles.

Getting a good three-dimensional image depends on the aptitude of the operator, the position of the baby and the amount of fluid around him or her. A good image of the face, for example, can only be obtained if the baby is facing upwards, he does not have his hands in front of his face and there is a pool of amniotic fluid surrounding the features.

Also, pediatric sonologists are reaping a variety of benefits from improved technologies. Patient care has been enhanced via higher-quality images in 3D. Costs, too, have been reduced due to a need for fewer rescans.
