3D-4D Ultrasound

3D ultrasound uses sound waves to create an image of a baby in the womb. However, unlike the flat images that 2D ultrasound provides, 3D ultrasound creates the impression of a 3D image of your baby. 4D ultrasound captures video of your baby moving, yawning, and even smiling in the womb. The only difference between the two is pictures versus an actual video.
