Orthovoltage to Monoenergetic Photon Beam Energy Correction Factor for HyperScint Scintillation Dosimeter

The HyperScint scintillator dosimetry system from MedScint is a small-field dosimeter with reported energy independence down to 100-keV. This work investigates the energy dependence of the scintillator between a monoenergetic photon source and polyenergetic orthovoltage beam.

A Novel Multi-Headed Scintillation Detector for Fast and Efficient Dose Measurements at Multiple Locations Simultaneously

To develop and quantify the performances of a novel multi-point scintillation detector (mPSD) having multiple heads connected to the same optical line, allowing real-time dose measurements simultaneously at 3 positions in non-contiguous space.

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.
