Fig. 13 — A: Plot of absolute deviation in DQE(0.5, X_min) vs. optical collection efficiency, $g_{7}^{c}$ . Minimum values were found to occur at $g_{7}^{c} = 0.36$ and $g_{7}^{c} = 0.18$ for mammography and radiography, respectively. B: Plot of chi-squared statistic value, $χ_{v}^{2}$ vs. grain size parameter, M. Minimum values of $χ_{v}^{2}$ were found to occur at M = 1.27 and M = 1.6825 for mammography and radiography, respectively.
