Feasibility study for high energy photon small beam dosimetry audits using OSL and RPL dosimeters

RPL and OSL dosimetry systems combined with practical dosimeter holders for accurate dosimeter positioning during irradiation were successfully tested in the feasibility quality audit study of small photon fields. Good agreement of small photon beam output factors measured for a range of field sizes with RPLDs, OSLDs and a pinpoint IC, with TPS calculated and the reference small beam output factor dataset were found. The film dose profiles and TPS modeled profiles matched very well indicating that the TPS was accurately modeled. The methodology for small beam dosimetry quality audit is planned to be assessed in a multicenter pilot audit study.
