2.4 Basic Principles

The principles of B mode scanning are as follows: human/animal organs have differing
densities and ultrasound speeds, i.e. their level of acoustic impedance varies (= average
density x acoustic speed). The piezoelectric crystal (transducer) is triggered by an electrical
pulse to produce an ultrasound wave of definite frequency. The ultrasound wave is
transmitted into the body. An echo wave is formed when the ultrasound wave passes through
the surface of different organs. These echoes, with different amplitudes, are received back via
the same transmitting transducer. The receiving echoes (acoustic energy) are converted into
electrical pulses. After the pulses are amplified, demodulated and DSC, etc., a standard video
signal is formed and a sectional image of the organ is displayed on the monitor screen.
