AI overview
# Ultrasound Overview Ultrasound is a medical examination technique that uses sound waves to create images of the inside of the body. It matters because it allows doctors to visualize internal structures and organs non-invasively, helping them diagnose conditions and monitor health without requiring surgery or radiation exposure.

Ultrasound is sound with frequencies greater than 20 kilohertz. This frequency is the approximate upper audible limit of human hearing in healthy young adults. The physical principles of acoustic waves apply to any frequency range, including ultrasound. Ultrasonic devices operate with frequencies from 20 kHz up to several gigahertz.
