Impact of range shifter material on proton pencil beam spot characteristics

Purpose: To quantitatively investigate the effect of range shifter materials on single‐spot characteristics of a proton pencil beam. Methods: An analytic approximation for multiple Coulomb scattering (“differential Moliere” formula) was adopted to calculate spot sizes of proton spot scanning beams i...
