Inside the Technology

What is 3D/4D ultrasound? 3D ultrasound is a technique used during pregnancy that displays three-dimensional images of a fetus. 4D ultrasound shows movement.

How does 3D/4D ultrasound work? A probe emits high frequency sound waves into the body, listens for the return echo and generates a three-dimensional image with movement.

How does 3D/4D ultrasound differ from 2D ultrasound? The computer programs that interpret and display the images differ in the 2D and 3D/4D formats.

Why do 3D/4D ultrasound images have a golden hue? The ultrasound machine has the capability to display the image in different tints. The golden hue is used frequently because it is pleasing to the eye and shows shadows and highlights.

How long has the 3D/4D technology been around? Ultrasound was first used on the human body for medical purposes in the late 1940s. 3D ultrasound was developed in 1987. 4D was developed about 2002.

Can 3D/4D ultrasound technology be used for more than just baby pictures? This developing technology is being used in some diagnostic medical procedures such as biopsies.
