| Abstract(in English) | The bioultrasonic spectroscopy system was developed for doing ultrasonic tissue characterization studies of biological specimens in the VHF/UHF range. The exponent on frequency of the velocity and the attenuation coefficient of biological media can be precisely measured using the system. In this paper, we report the results of investigations of the relation between the exponent on frequency and the relaxation parameters. In order to carry out numerical calculations, a model for a single relaxation process is employed. The results of the calculations revealed the relation between the exponent on frequency and the parameters of the single relaxation process. From the measured velocities and attenuation coefficients of a 25% aqueous solution of glucose in the frequency range 20 to 700 MHz, the relaxation parameters were determined. |
