Development of a novel multi-point plastic scintillation detector with a single optical transmission line for radiation dose measurement

The goal of this study was to develop a novel multi-point plastic scintillation detector capable of measuring the dose accurately at multiple positions simultaneously using a single optical transmission line. This study demonstrates the practical feasibility of multi-point plastic scintillation detector. This type of detector could be very useful for pre-treatment quality assurance applications as well as an accurate tool for real-time in vivo dosimetry.

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

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

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.
