Resumo(s)
In this paper we address the numerical solution of the inverse elastography problem, from the knowledge of
the excitation field on the boundary and the displacement field in a grid of points within the domain. We
suggest using a representation of the solution by the method of fundamental solutions and using a Newtontype
method to iteratively approximate the Lam´e coefficients of the medium from elastography displacement
measurements. We consider a toy model to illustrate the performance of the method.
