Paper Abstract

Optical coherence elastography (OCE) provides deformation or material properties mapping of soft tissue, which is important for morphological and pathological studies of the tissue. An OCE technique is developed based on digital image correlation. System calibration and measurement error evaluation are performed. The displacement measurement of 0.6 μm to over 100 μm was obtained through a phantom experiment. The capability of this OCE technique for differentiation of stiffness was evaluated by imaging a two-components phantom. OCE imaging of an aneurysm sample shows promising results for characterization of composites of aneurismal wall in the future.
