Paper Abstract

Dynamic optical coherence elastography (OCE) is expected as new diagnostic technology of near tissue surface. However, few studies about shear wave propagation in inhomogeneous medium have been reported although human tissue is inhomogeneous medium. In this report, estimation of shear wave speeds and strain images of inhomogeneous medium were studied using swept-source optical coherence tomography (SS-OCT) system. Firstly, the shear wave speeds of four-layered chicken sample were measured. Secondly, OCT images of tissue mimicking phantoms, which included thread and aluminum wire were measured and strain distributions were calculated by PIV. Reflection and artifact of strain images were discussed.
