Ultrasound Facts and Information
What is the difference between an ultrasound and a sonogram?
An ultrasound is the machine that allows you to see your baby during
your pregnancy. A sonogram is the picture taken of your baby during the
ultrasound. A sonogram is a "still-shot" of your baby. 4D
Ultrasounds take 3D ultrasound images, or 3D sonograms, and adds the
element of time to the process. The result: Live Action ultrasound
images of your baby. Some people refer to the procedure as a 3D scan or
4D scan.
