Accuracy of Common Motion Estimators in Wave-Based Optical Coherence Elastography

Abstract

Motion estimators are commonly used in shear wave optical coherence elastography to compute small displacements. This work focuses on comparing three motion estimators: Kasai, Loupas, and the vector method. Our results show that the vector method is superior in low-SNR, low-amplitude situations for group velocity calculation and profile reconstruction. © 2021 Journal of Biomedical Photonics & Engineering.
