Feasibility study of utilizing XRV-124 scintillation detector for quality assurance of spot profile in pencil beam scanning proton therapy

Spot scanning proton therapy provides more conformal target dose distributions compared to the uniform scanning and double-scattering proton beam delivery techniques. [1,2] However, an unwarranted change in spot size and spot position can affect the quality of treatment beam delivery and patient treatment plan [3]. Therefore, the size and position of a pencil proton beam are measured as a part of quality assurance (QA) program [2].
