Impact of estimating local spatiotemporal correlation (LSTC) image from temporally downsampled Doppler ensemble. (a‐h) and (i‐p) corresponds to two examples of in vivo thyroid microvascular blood flow imaging, displayed in Figs. 6 and 7, respectively. Left and right columns of each thyroid example correspond to the Doppler ensemble without and with motion correction, respectively. The line‐plots (a,b,i,j) display the mean LSTC estimated from a temporally downsampled ensemble, with 10–100$\text{\%}$ of Doppler frames. Error bars are estimated across 10 random sampling of temporal frames from the Doppler ensemble. (c,f,k,n), (d,g,l,o), and (e,h,m,p) display representative LSTC images obtained with 10, 50, and 100$\text{\%}$ of ensemble frames. Color bar for (c‐h) and (k‐p) are uniform.
