    Abstract

    In this paper, we introduced the combined acoustical and optical method for imaging the propagating shear waves and mapping the shear modulus with a high resolution that is comparable to optical coherence tomography (OCT). The mechanical waves propagation is dynamically imaged with phase-sensitive OCT (PhS-OCT) with an equivalent frame rate of ∼47 kHz. The 2-D elastography image is retrieved from measuring the shear wave velocity in the imaging region. The quantitative accuracy of this method is examined by validating experiments on agar phantoms.
