Comparisons between calculated (SG, DG-EFP, and DG fluence models) and measured FSFs of square fields. Positive values in percentage differences represent calculated FSFs larger than measured ones. For FSFs, dotted-dashed lines: SG; dashed lines: DG-EFP; solid lines: DG; and squares: measured. For percent differences, dotted-dashed lines with circles: SG; dashed lines with triangles: DG-EFP; and solid lines with diamonds: DG. (a) and (b) for energy of 72.5 MeV (4.0 cm range) at depths of 2.0 and 3.7 cm; (c) and (d) for energy of 148.8 MeV (15.2 cm range) at depths of 2.0 and 15.0 cm; (e)–(g) for energy of 221.8 MeV (30.6 cm range) at depths of 2.0, 30.0, and 23.2 cm, respectively.
