title = "Power Law Behavior of Shear Waves Measured in Swine Liver",
abstract = "To characterize the attenuation and dispersion behavior of shear waves in excised swine liver samples, complex shear modulus values are measured with a Rheospectris C500+ from 10 Hz to 2000 Hz. The shear wave attenuation and shear wave speed are then calculated from the complex modulus measurements. A power law fit is evaluated for the shear wave attenuation, and a power law fit with a constant offset is evaluated for the shear wave speed. The power law closely matches the measured shear wave attenuation over most of the frequency range evaluated, although some differences are observed at lower frequencies. The power law with the constant offset closely matches the measured shear wave speed in all measurements. The results demonstrate that shear wave attenuation and shear wave speed in swine liver follow a power law.",
