Synthetic schlieren tomography is an optical technique to measure ultrasound pressure fields. Prior to reconstruction of the pressure, images of a photographed target with and without perturbations caused by the ultrasound are analyzed with optical flow methods. In this talk, Bayesian formulation of a Horn-Schunck type optical flow approach is utilized. Displacement field is estimated and compared to traditional approaches. Impact of the approach on estimation of entire pressure field is assessed.
