Intensity threshold contouring of the epithelium for each OCT system. Representative ROI and contoured ROI of (a,b) SS-OCT 1310nm 200kHz VCSEL system and microscope scanning probe, (c,d) SS-OCT 1700nm 90kHz system and microscope scanning probe, (e,f) SS-OCT 1310 50kHz system and flexible side viewing endoscope (g,h) TD-OCT 1310nm 254Hz system and flexible forward viewing endoscope (I,j) SS-OCT 1310nm 50kHz system and rigid forwarding viewing endoscope (k,l) SS-OCT 1310 nm 200 kHz VCSEL system and rigid side viewing endoscope. Yellow contour and yellow arrow denotes epithelium, purple asterisk denotes basement membrane, blue arrow denotes superficial lamina propria, and orange arrow denotes deep lamina propria. Red scale bars denote 200μm of axial distance.
