Figure 5

Dynamic OCT imaging of a 2-week obstructed kidney model for 6 mm \(\times\) 6 mm field of view. Cross-sections from (a) scattering OCT, (c) LIV, and (e) Fast-DOCT imaging; (b, d, f) En face slices of the OCT, LIV, and Fast-DOCT images at the depth location indicated by the horizontal line in (a); (g, h) microscopic and macroscopic views of H &E stained histological micrograph; The arrowhead in (a) indicates the depth location of the histology (g). The circles in (d, f) indicate artifact due to the specular reflection from the surface. The white arrowheads in (c, d) represent a high-LIV superficial layer. The arrows in (g) represent structural damage and dilation in the renal tissue. LIV log-intensity variance, Fast-DOCT fast dynamic OCT. Scale bar 1 mm.
