An ultrasound uses high-frequency sound waves and a computer to create images of organs, blood vessels, soft-tissues, or of pregnancy. These sound waves are transmitted to the body through a transducer. A warm gel is applied to the skin for better transmission and reception. The sound waves return as echoes and are recorded as images on a computer monitor. Ultrasound is commonly used to perform obstetric, breast and thyroid scans, and to diagnose diseases of the blood vessels or to determine causes for abdominal and pelvic pain.
