Echocardiography

The technique of echocardiography is based on the reflection property of ultrasonic waves. An echocardiogram is a type of ultrasound test that uses high-pitched sound waves that are sent through a device called a transducer. The device picks up echoes of the sound waves as they bounce off the different parts of our hearts. These echoes are turned into moving pictures of our hearts that can be seen on a video screen.
