Doctors are able to make sonograms through the use of ULTRASOUND.Ultrasound.
In a sonogram, ultrasound waves are sent to the part of your body being examined, and these waves are displayed as images.

Sonograms are also used to allow pregnant women and their doctors to see a baby before it is born.
