Echo Machine

Echo is a test used to evaluate condition of heart by being able to view its structure. It is a non-invasive technique that makes use of sound waves to capture cardiac images. 2D Echo is also called as echocardiography, cardiac ultrasound, Doppler ultrasound and cardiac ultrasonography. Sonar is the technique that is used in 2D Echo to view internal structure of heart. In this technique, sound waves are passed through body and these get reflected back once they strike against an obstruction. With the help of computer, images can be traced out.
