Benjamin Insley is a PhD’s student in medical physics at the The University of Texas MD Anderson Cancer Center UTHealth Graduate School of Biomedical Sciences, he is actually studying the use of scintillator for ultra small field dosimetry in low energy (KV) photons.
As he confirms the good fit of the correction factors for our HYPERSCINT scintillation detector between monoenergetic beams and a polyenergetic orthovoltage beam, his intention is to continue his study with experimental data.
Definitely someone to follow for low-energy and small-field radiotherapy applications! Future work will include adding insensitive components to the simulation (such as the stem) that may scatter dose into the active volume in an energy-dependent manner.
Successful e-poster at AAPM 2022 meeting
Take a look at his PO-GePV-T-270 e-poster presented during the AAPM 2022 conference online to understand how plastic scintillators can help performing dosimetry of low energy photon beam.

Purpose: 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.
