Abstract
In order to obtain quantitative mechanical properties of tissue non-invasively, we propose in this work an inverse approach by which the spatial distribution of the relative shear modulus of tissue can be estimated from the measured axial and lateral deformation using angular insonifications. Measurements on PVA phantoms and the procedure to obtain the shear modulus are described.
