Scattering coefficient extraction algorithm. (a) Original OCT image obtained from OCT system. In (b), the A-lines are averaged and plotted as a function of depth, with intensity normalized to 1. Natural logarithm of the intensity for the urothelium is taken in (c). User is also prompted to select linear region in (c). Linear regression analysis is performed in (d) and algorithm returns scattering coefficient, , range of fit, , and correlation coefficient, .
