Abstract

The calculation of dispersion curves and, therefore, the rheological properties is possible by analyzing how the different phase velocity modes behave in the medium of interest. Shear wave propagation in 'thin' organs is affected by the mechanical properties of the tissues surrounding those organs. In order to obtain the proper mechanical properties of such boundary sensitive organs, an analytical solution for the dispersion curves in a plate surrounded by semi-infinite solids was derived and validated in DISPERSE software, FEM simulations and experimentally in PVA phantoms.
