Fig. 6. Polarization-sensitive (PS) OCT of poorly differentiated carcinoma with surrounding fibrosis in ex vivo lung. (A) Structural OCT does not clearly show a distinction between solid carcinoma and adjacent fibrosis. Calcifications within the fibrosis can be seen as signal-poor structures (C). (B) PS-OCT shows a clear delineation between solid carcinoma (left of line) and fibrosis (right of line), with no birefringence signal in the regions of carcinoma and high birefringence signal in the regions of fibrosis. (C) Matched histology confirming the demarcation between carcinoma and fibrosis. Scale bars: 1 mm. Figure reprinted with permission from Reference 39.
