Non-Invasive Cardiovascular Sonography (NICVS), also called Echocardiography (or Echo), is a diagnostic modality used for medical imaging of heart & blood vessels. It is a powerful tool that can offer a wealth of information about the human heart and peripheral blood vessels. Echocardiography (cardiac ultrasound) is performed by using a specialized scanner called transducer (or probe) which is connected with the echo machine. The transducer, after attaching to the skin of the chest, produces high frequency sound waves (ultrasound) which are transmitted into the human body. These ultrasound waves reflect from heart/blood vessels to the transducer. From transducer the sound waves are then transformed into images on the screen of echo machine. These cardiovascular images provide valuable information for diagnosing and treating variety of heart and blood vessels diseases. Therefore Cardiovascular Sonography has become the most widely used imaging modality in modern medicine and it will continue to expand.
