In this study, we developed an all-in-one phantom and scintillator radiation sensor (PSRS) with plastic scintillating fibers which can measure the real-time position and the dose distribution of Ir- 192 as a radioactive source employed in high-dose-rate (HDR) brachytherapy. As experimental results, we simultaneously obtained information on the shape and position of the Ir-192 as well as the dose distribution. The all-in-one PSRS system has many dosimetric advantages, such as realtime monitoring, wide dose-response range, high spatial resolution, nearly water-equivalence for high-energy photons, and the ability to measure two-dimensional dose distribution.
