In ultrasound procedures, high-frequency sound waves are used to create a moving image, or sonogram, on a television screen. Ultrasound images can be used to diagnose infertility and other medical problems. Often carried out at various stages of pregnancy, ultrasound scans can help to identify multiple fetuses and detect anomalies.

Ultrasound is cyclic sound pressure with a frequency greater than the upper limit of human hearing. Ultrasound is thus not separated from "normal" (audible) sound based on differences in physical properties, only the fact that humans cannot hear it. Although this limit varies from person to person, it is approximately 20 kilohertz (20,000 hertz)..
