Validating a double Gaussian source model for small proton fields in a commercial Monte-Carlo dose calculation engine

Validating a double Gaussian source model for small proton fields in a commercial Monte-Carlo dose calculation engine

Purpose: The primary fluence of a proton pencil beam exiting the accelerator is enveloped by a region of secondaries, commonly called “spray”. Although small in magnitude, this spray may affect dose distributions in pencil beam scanning mode e.g., in the calculation of the small field output, if not...
