63 Characterization of a scintillation dosimetry system for in vivo dose verification in brachytherapy

Introduction. In vivo dosimetry allows detection of potential treatment errors. In brachytherapy, the presence of high-gradient dose distribution and potentially large dose rate depending on the type of source imposes new challenges for in vivo dosimetry. The aim of this work is to characterize a new scintillation detector for this type of measurement.
