  In this paper, we consider the problem of estimating the internal
displacement field of an object which is being subjected to a deformation, from
Optical Coherence Tomography (OCT) images before and after compression. For the
estimation of the internal displacement field we propose a novel algorithm,
which utilizes particular speckle information to enhance the quality of the
motion estimation. We present numerical results based on both simulated and
experimental data in order to demonstrate the usefulness of our approach, in
particular when applied for quantitative elastography, when the material
parameters are estimated in a second step based on the internal displacement
field.
