Title: Viscoelastic Registration of Medical Images

Speaker: Takuya Okamoto

Date: Thu. May 20th, 1:00 pm

Abstract:
Since the physical behavior of many tissues is shown to be viscoelastic,
we propose a novel registration technique for medical images via
physical principles of viscoelasticity. It allows the template and the
target images to differ by large local deformations like viscous fluid and
small local deformations like elastic solid. With an extra elastic term
introduced, the proposed model constrains the transformation by
coupled viscoelastic behavior and therefore reduces the smearing
effect caused by the fluid terms. We apply our approach to both
artificial test data and MR brain slices yielding accurate registration
results.
