Paper Abstract

Resolution and contrast of optical coherence tomography (OCT) images are degraded by multiple scattering processes that give a speckled appearance. In this paper we examine the spatial-frequency characteristics of tissue structure and speckle, with the goal of distinguishing speckle form structure for noise reduction by wavelet-based algorithms. Real and simulated images provide the basis for evaluating the performance of the algorithms and the finite-difference time-domain algorithm simulates propagation of the backscattering waves in OCT system.
