Figure 11
Comparisons of experimental (green) and simulated (blue) spectral distributions, for four pairs of detector pixels positioned either side of the y = x line of symmetry. The metric is displayed for the ROI that spans the summation of the Compton and elastic back-scatter ROIs. The spectra for pixel numbers #74, #178, #78 and #182, in the upper-right quadrant, are shown for incident beam energies of (a) 11.0 and (b) 6.8 keV. |
