Acoustic properties of selected bovine tissues in the frequency range 20-200 MHz.


The acoustic properties of freshly excised bovine liver, heart muscle, and fat are characterized in the frequency range 20-200 MHz by the bioultrasonic spectroscopy system using an ultrasonic transmission comparison method. Significant differences are obtained in the attenuation coefficient, velocity, impedance, and density among these tissues. Measurements… (More)
