Ultrasound nonlinearity parameter (B/A) in biological tissues.
The ultrasonic nonlinearity parameter B/A is determined using the finite amplitude distortion method. The generation of second harmonic as a result of propagation of ultrasonic wave through the media, were measured by the receiving transducer (4.0 MHz) placed coaxial with the same sized cylindrical transmitting transducer (2.0 MHz). The second harmonic component of the wave, were analysed and recorded. The values of B/A of liver, kidney, spleen and heart tissues turns out to be 7.48, 6.75, 9.89 and 6.45 respectively.
