Fig. 2From: Monte Carlo simulation of the Varian TrueBeam flattened-filtered beams using a surrogate geometry in PRIMOAngular distribution calculated for the TB (red) and CL21 (blue) phase spaces simulated with penelope transport parameters C1 and C2 as specified in table 1. For comparison purposes, the angular distribution obtained for CL21 with transport parameters C1 and C2 equal to \(10^{-3}\) is also plotted for each nominal energy (green). Statistical uncertainties are not shown for the sake of better visualizationBack to article page
