Ultrasound imaging or Sonography is used often in medicine. Instead of radiation, the procedure uses high-frequency sound waves to look at organs and structures inside the body.

Ultrasounds are sound waves with frequencies higher than the upper audible limit of human hearing. Ultrasounds are not different from 'normal' (audible) sounds in their physical properties, only in the fact that humans cannot hear it - but even this limit varies from person to person.

Ultrasound devices operate with frequencies from 20 kHz up to several gigahertz. Health care professionals use it to view blood vessels, the heart, kidneys, liver, and many other organs in the body. Doctors most frequently use ultrasounds during pregnancy to view the fetus as it presents a safe, clear picture of the fetus and mother's body.
