Fig. 7 — (a) Background signal was calculated from the average of 100 frames (1). The averaged frame was then averaged down columns creating a profile of the frame (2). Background regions were selected and averaged from the profile (3). (b) The percent change from the background signal provided a measure of contrast. Plots show the percent change for the articulating arm (top) and fiber bundle (bottom) at three source-detector (S-D) separation distances. (c) Contrast and noise plots for each configuration.
