Shear wave elastography has attracted attention because of its possibility for quantitative measurement of tissue elasticity. However, conventional methods for shear wave elastography have shortcomings. To solve the shortcomings, we propose a new scheme for shear wave elastography, in which tissue elasticity is measured only at tumors using the shear wave generated by the mode conversion of a longitudinal wave. In this study, as a fundamental examination, we investigate the suitable frequency and incident angle of a longitudinal wave for generating the shear wave through finite element method (FEM) simulations.
