Résumé
In this study, we evaluated the stability and reliability of absorbed dose-to-water for an HDR The sandwich setup phantom was designed with a dedicated device for two ion chamber measurements of absorbed dose-to-water for a mHDR-v2r The measured doses at sandwich setup phantom agreed within 1.0% with AAPM TG-43 protocol. In all measurement fractions, the temporal variations of measurement value were less than 1.0%, and the intra-rater reliability were 0.94% or more. The measurement value obtained by the absorbed dose-towater had good reliability, and sandwich setup phantom is potentially useful and convenient for daily dose management of
