Ultrasound uses high frequency sound waves (like a radar) to create images of the inside of the body. It is completely safe for pregnant women and for children. Pictures are obtained by placing an ultrasound transducer (a microphone) against the body. A small amount of gel is placed on the skin. The exam is painless.
