AF/OCT system for imaging excised tonsils placed between glass slides, BDM: broadband dielectric mirror, DBS: dichroic beamsplitter, APD: avalanche photodiode.
Figure 2.
Comparing OCT B-scans with histopathology results, DCT: dense connective tissue, Epi: epithelium, Cr: crypt, LN: lymphoid nodules, and GC: germinal center. White bar is 100 µm.
Figure 3.
Middle row are enface OCT sections, top and bottom rows are OCT B-scans corresponding to the green and blue dashed lines, respectively; Cr: crypt.
Figure 4.
Imaging results obtained from AF/OCT scans of three tonsils samples, including representative enface OCT (a1-3), green AF images (b1-3); Cr: crypt, DCT: dense connective tissue, LN: lymphoid nodules.
Figure 5.
AF/OCT scan of thin tonsil section.
(a) AF image and (b) representative enface OCT section from a thin section cut from a tonsil sample along with the histopathology result (c) obtained from a 4 µm thick section cut from the same sample Cr: crypt, LN: lymphoid nodules, and DCT: dense connective tissue.
