Investigations of a Novel HyperscintTM Plastic Scintillator Detector and Hyperspectral Analysis Approach in a 74 MeV Proton Beam

The HYPERSCINT novel plastic scintillator with spectral analysis approach dosimetry system shows potential for dose measurement in a 74 MeV proton beam with negligible stem effect. The Cerenkov free spectrum may be used to facilitate calibration of the device in MV x-ray beams to improve Cerenkov removal and performance in small field dosimetry.

Review of plastic and liquid scintillation dosimetry for photon, electron, and proton therapy

While scintillation dosimetry has been around for decades, the need for a dosimeter tailored to the reality of modern radiation therapy-in particular a real-time, water-equivalent, energy-independent dosimeter with high spatial resolution-has generated renewed interest in scintillators over the last 10 years. This topical review is intended to provide the medical physics community with a wide overview of scintillation physics, related optical concepts, and applications of plastic scintillation dosimetry.
