Abstract

A graphical examination of tabulated attenuation coefficient data appears to suggest that the frequency dependence of attenuation coefficient could be more properly described by a higher ordered function for some tissue types. Attenuation coefficient measurements performed in this study used the radiation force balance technique. Fresh tissues were used in these measurements which were made at room temperature (20-22 degree C). The tissues measured included bovine spleen and pancreas, porcine spleen and liver, and sheep liver. Their ultrasonic attenuation coefficient also seemed to indicate a frequency dependence that could be described by a higher ordered function.
