Estimation of spatiotemporal correlation matrix (STCM) and local spatiotemporal correlation (LSTC) image from Doppler ensemble. (a) Acquired Doppler ensemble, (b) local kernel indicated in blue in (a), (c) STCM of the local kernel in (b), (d) LSTC image represents the mean of the STCM, estimated by the moving the kernel across the entire imaging plane. The size of the representative 3D kernel is purposefully exaggerated for better visualization.
