Background, Motivation and Objective In traditional shear wave elasticity imaging (SWEI), shear wave velocity is measured away from the acoustic radiation force (ARF) axis. Instead, we measure the time-topeak displacement of tissue directly along the ARF axis (see blue arrows in figure below). Measuring displacements along this axis rather than off-axis simplifies hardware required for quantifying tissue stiffness. Previously this method has been demonstrated, but the variance was too high for practical feasibility. To reduce stiffness estimation error, we apply our Bayesian displacement estimator.
