Figure 3.
Plots of GATE simulation results: (a) Average full‐width‐half‐maximum plotted against pinhole‐diameter. Ellipsoid case is interpolated to show that, for same average resolution for 5 mm diameter for the Flat detector case, an 8.68 mm diameter may be used for the Ellipsoid case. (b) Sensitivity with respect to 5 mm diameter case (i.e., d2/25) is plotted vs the average FWHM from GATE measurements. These imply a 3.06 times sensitivity improvement.
