Figure 9: PS-OCT imaging of biceps tendon. The OCT images (top) are of biceps tendons imaged at two different polarization states. OCT effectively demarcates the layer of the tendon. The banding pattern is from the polarization sensitivity that changes with the manipulation of the polarization state, which is indicative of highly organized collagen. The picrosirius red stained sample (lower) demonstrates organized collagen by staining with intense yellow/orange color. Image courtesy of Martin et al. [10].
