Table 13 Comparison of the percentage of lateral dose profile points passing the 1%/1 mm criteria for the two energy FWHM configurations at 0.120 MeV and 0.140 MeV at various scan depths. The initial electron beam energy is fixed at 10.5 MeV, the focal spot FWHM and beam divergence are at default values of 0. The number of histories is 2.5 × 107
