Fig. 1From: Pilot study on the effects of preservatives on corneal collagen parameters measured by small angle X-ray scattering analysisPhoto images of 2D small angle X-ray scattering patterns produced by frozen and thawed control corneas and the preserved corneas. The graph shows the intensity profiles over the measured q-range for all the samples. Arrow indicates peak (0.045–0.055 Å−1) used to determine D-spacing and the full q-range (0.01–0.1 Å−1) for the fibril diameterBack to article page
