  1. Geant4 Accuracy and Benchmarking Bruce Faddegon, UCSF

  2. Geant4 e-/x-ray RT benchmarks • SLAC • Makoto Asai • Tsukasa Aso • Joseph Perl • Jane Tinslay

  3. Thick-target bremsstrahlung measurement at 10-30 MV • Subtract pile-up spectrum and bkg • Add counts lost to pulse pile-up • Unfold detector response • Add counts lost to attenuation and detector efficiency • Collimator effect BA Faddegon, CK Ross, DWO Rogers, Medical Physics 17(5):773-785, 1990 BA Faddegon, CK Ross, DWO Rogers, Medical Physics 18(4):727-739, 1991
