Abstract

Data have been obtained on the ultrasonic attenuation coefficient, absorption coefficient, and velocity in the livers of control and experimental animals as a function of time on a high alcohol diet known to produce fatty livers. The attenuation coefficient, based on measurements with two different systems, and the absorption coefficient in the livers from the experimental animals increased with time on the diet. Additionally, a comparison of the attenuation coefficient at 1 MHz and at room temperature as measured with the radiation force technique and the absorption coefficient at 25 degree C show that they are nearly the same, suggesting that losses due to scattering are a small part of the total loss. The velocity as measured with the acoustic microscope appears to decrease with time on the diet.
