In order to evaluate the properties of ultrasonic nonlinear scattering, the ultrasonic attenuation characteristics using the second harmonic component of the transmitted ultrasonic signal through normal and fatty hen liver as well as the fundamental component were measured. In The experiment, a 50MHz transducer was by reflection method and its frequency dependency was analyzed. The second harmonic component was detected by using pulse inversion detection technique. The experimental results showed that the attenuation coefficient was almost constant around second harmonic frequency dependence can identify the property of normal and fatty hen liver.
