Ultrasound is a technique that uses sound waves to take a picture of the baby (fetus) in the uterus. Because it uses sound waves instead of radiation, ultrasound is safer than X-rays.
Ultrasound works by bouncing sound waves off the developing fetus. Echoes from the waves are converted into an image - called a sonogram - on a TV monitor. The technique is sometimes called sonography or sonar.
Ultrasound has become an increasingly important part of prenatal care, providing information that can guide a physician's care for a pregnant woman and improve the outcome of pregnancy.
