Abstract

We propose a new estimation method of tissues stiffness from deformation induced by arterial pulsation. The new method was named Intrinsic Elastography (IE). Under two assumptions that the deformation induced by pulsation propagates throughout the body, and the propagation velocity (PV) is closely related to the mechanical properties of tissues, the IE can evaluate the tissue stiffness based on the PV. However, this method has an issue that the observed PVs change with the changes of amounts of the flow. In this paper, we propose the new estimation method in order to estimate true shear elasticity in spite of the changes. The results was compared to the results of SWI. The results was almost identical to the result of SWI, or showed the similar results.
