N2 - Current elastography techniques can measure mechanical properties of soft tissues by estimating the elastic shear modulus, μ0. Recently, the assessment of tissue nonlinearity using acoustoelasticity (AE) has shown some promising results in differentiating healthy from malignant tissue by estimating a third-order nonlinear coefficient A. To fully characterize the nonlinear properties of the tissue, it may be necessary to develop techniques to also reliably estimate the fourth-order elastic constant D as the combination with the other parameters μ and A could provide diagnostic discriminatory power. This study evaluates the implementation of a three-parameter fit (μ0, A, D) to estimate the nonlinear properties of ex vivo kidneys using the shear modulus, μ vs. strain, estimates obtained when the phantoms are subjected to compression.
