Ultrasound is a medical procedure that uses sound waves to create images of the inside of the body. It's a safe and non-invasive way to look at organs, tissues, and blood vessels. Ultrasound can be used to check on a baby growing inside a pregnant woman, to look for abnormalities in organs like the liver or kidney, or to see if there are blood clots in veins. Doctors and other medical professionals who specialize in using ultrasound are called sonographers, and they use special machines to create the images.
