Mode B Scanner principle
Human organs are different in their densities and ultrasound speed, i.e. they have a different acoustic impedance. The piezoelectric crystal (transducer) is excited by the electrical pulse to produce an ultrasound wave of definite frequency. This ultrasound wave is transmitted into the human body. The echo wave is made when the ultrasound wave passes through the surface of different organs. Echoes with different amplitudes are received via the same transmitting transducer. Received echoes (acoustic energy) are converted into electrical pulses which are amplified, demodulated and DSC, etc. A standard video signal is generated allowing the organ section image to be displayed on a monitor screen.
