An ultrasound allows you to see your baby during your pregnancy. A picture taken of your baby during the ultrasound is called a sonogram. A sonogram is a little picture of your baby. 3D sonograms are created when 4D Ultrasounds take 3D ultrasound images and add the element of time to the process. Also know as 3D imaging, a 3D scan, or 4D scan.
