  • Abstract : Optical coherence elastography (OCE) is an imaging modality that maps mechanical properties by using optical coherence tomography (OCT) to measure tissue displacement after mechanical excitation. From OCE elastograms, quantified elasticity mapping can be accomplished using an appropriate mathematical model of the tissue. In this talk we present a mathematical model to reconstruct the mechanical properties of an elastic medium, in the OCE imaging technique. We formulate the inverse model problem as a PDE-constrained optimization problem, where the objective function measures the discrepancy between observations and predictions. We will discuss different strategies for learning the space varying elasticity coefficients.
