| Abstract(in English) | We have confirmed to identify a fatty hen liver characteristic when 30MHz to 70MHz ultrasound passes the specimen. Energy is thought to be absorbed by hydrolysis in the constituents of the tissue and by the relaxation process at low frequency and by relaxation process of motions of side chain alone at high frequency. We describe a study on a fatty hen liver in the relaxation process of tissue characterization by analyzing the ultrasonic absorption spectrum and the attenuation of a second harmonic component. Results showed that the attenuation of a fatty hen liver was increased linearly by each absorption between 60 and 140 MHz band. |
