Human microcirculatory flow velocity mapping.
(a) Conventional SDF image where the contrast is based on absorption differences between RBCs and tissue. Flows below 2 mm/s can be measured by RBC tracking. (b) 1/τc map of the same microcirculation region obtained with multi-exposure SDF-LSCI after correction for τc,offset, contrast is obtained by perfusion dynamics. (c) Map of LSCI-derived blood flow velocities after correction for τc,offset and A(N) and masking of selected blood vessel contours. The scale bar is 100 μm.
