A Kelvin-Voight Fractional Derivative Model for Viscoelastic Characterization of Liver Tissue

摘要

There has been interest in the mechanical properties of the non-load bearing soft body tissues (brain, liver, prostate etc.) in recent years. The motivation comes from three areas: characterizing tissue response to crash injuries [1], modeling for robotic surgical devices [2] and elastographic diagnosis of disease processes using ultrasound [3].
