An ultrasound scan, also referred to as a sonogram, diagnostic sonography, and ultrasonography, is a device that uses high frequency sound waves to create an image of some part of the inside of the body, such as the stomach, liver, heart, tendons, muscles, joints and blood vessels.ltrasound is used to create images of the fetus or embryo in the uterus. Today, often referred to simply as an ultrasound scan, it is part of standard prenatal care.
The principle of an ultrasound scan is to direct ultrasound waves into the body, which then pass through various tissues and are partially reflected at each boundary where the wave speed changes. These reflected waves are then detected and are used to construct an internal image of the body.
