Figure 1: Cartilage OCT form birefringence. (a) OCT image of cartilage with OCT form birefringence where distinct dark bands create a multilayered appearance. (b) OCT image of cartilage without OCT birefringence. In cartilage graded to be without OCT form birefringence, there were no recognizable banding patterns in any of the four scan orientations. Scale bar = 1 mm.
