What is ultrasound?

Ultrasound , also known as Sonography, is a method of medical imaging that uses sound waves to image the soft tissues inside the body. Sound waves pass through the body and according to their frequency, the signals are converted into images on the computer. Ultrasound can also be used for tissue or fluid sampling.
