Dosimetric Characterization of the HYPERSCINT Scintillation Dosimetry Research Platform for Multipoint Applications

SMALL-FIELD, MV Photon, Multi-point Show more

Multipoint detectors are very interesting toward developing new phantoms and making measurements in constrained space. This study aims at assessing the performance of the HYPERSCINT dosimetry research platform (Medscint inc., Québec, Canada) with a high spatial resolution 3-point plastic scintillation detector for application to high energy photon beam dosimetry.

Development of An Automated Routine for Finding the Precise Location of Scintillators Elements and Their Emission Spectrum in a Multi-Point Scintillation Detector

Advanced Optical Dosimetry, MV Photon, Multi-point Show more

The goal of this study is to develop an approach allowing for calibration of multi-point scintillation detector (mPSD) using only the photon beam from a linear accelerator such that it doesn’t depend on the availability of other irradiation modalities (e.g. orthovoltage irradiators). This study also aims at determining an experimental method to validate the spatial position of the different scintillators within the mPSD.
