Ultrasound is a machine which uses the principle of reflection of high frequency waves from objects, pretty much similar to what is used in submarines or by bats. The reflection ascertains whether the tissue is solid or liquid as in the case of lumps or cysts by the use of this mechanism based on the objects echogenecity.
Let us know if you have any other queries.
