Estimates from: (a) the LE-method, WSS_LE (VENC = 2 m/s), (b) the wall-based method, WSS_Wall (VENC = 2 m/s) and (c) the FVE-method, WSS_FVE (velocity resolution = 0.15 m/s). The vertical axis shows the estimated WSS and the horizontal shows the true WSS. The error bars show the standard deviation due to voxel position relative the wall and segmentation (only WSS_Wall) errors.
