Multi‐institutional survey of source modeling parameters for proton pencil beam scanning treatment planning system commissioning

The reference data provided in this work will help to cross-check the beam model during treatment planning system commissioning. Furthermore, this information is useful for Monte Carlo applications and research, where beam characteristics are required to set up phase space parameters, thereby avoiding the need to model the entire PTS. Finally, the results of this study will have indispensable educational value by providing valuable insights into the characteristics and capabilities of different PTSs.
