Ultrasound - the name of equipment that produces many types of sound which can be used for imaging and/or treatment. It has many medical applications. For example, a Foetal Ultrasound produces images of a baby in the womb. A Doppler Ultrasound is used to see if blood is flowing as it should, e.g. there are no restrictions in blood vessels. It can be used to break up Ureter/Kidney Stones without surgery and without disturbing surrounding tissue. (Advanced computer technology can enhance the images produced e.g. show them in 3D colour).
