 Doppler echocardiography

Doppler echocardiography is a specialized ultrasound technique used in cardiology to assess the heart's function and blood flow through its chambers and valves. It employs the Doppler effect, which is the change in frequency of sound waves in relation to an observer moving relative to the source of the waves. In the context of echocardiography, high-frequency sound waves are emitted from a transducer placed on the patient's chest.
