RCs and curve fits for the four image protocols with the 30 × 4 reconstruction and a 12-mm Gaussian filter. The equivalent figures for the other reconstructions can be found in the supplementary material. ME 239 keV is in panel a, ME 79 keV is in panel b, HE 239 keV is in panel c, and HE 79 keV is in panel d. Both RCmax and RCmean data points are plotted, in addition to a curve fit to RCmean
