Ultrasound technology is a medical imaging technique that uses high-frequency sound waves to produce images of internal organs and structures within the body. Ultrasound is commonly used to monitor the growth and development of fetuses during pregnancy, as well as to diagnose and treat a variety of medical conditions such as heart disease, gallstones, and tumors. The technology is non-invasive, safe, and provides real-time images which can be used for diagnostic purposes. Ultrasonography is also used in various other fields such as industrial testing, veterinary medicine, and underwater exploration.
