Echocardiography

Echocardiography is an ultrasound examination of the heart.

Principle: detection of UZ reflection occurring at the interface of cardiac structures of different density. The ultrasound signal is created in the piezoelectric crystal by changing electrical pulses into mechanical waves of 2–10 MHz. The converter in the probe serves as a transmitter and receiver of UZ signals.
