Characterization of a 0.8 mm³ Medscint Plastic Scintillator Detector System for Small Field Dosimetry

The scintillator-based dosimetry system HYPERSCINT RP-200, coupled with a 0.8 mm³ plastic scintillator detector, demonstrated excellent dosimetric properties for small field radiation therapy, including good repeatability, dose linearity, and accuracy down to field sizes as small as 0.5 × 0.5 cm².

Performance of the HYPERSCINT scintillation dosimetry research platform for the 1.5 T MR-linac

This study demonstrates the suitability of the HYPERSCINT PSD for accurate time- resolved dosimetry measurements in the 1.5 T MR-linac. The excellent performance during continuous MR scanning and during dynamic movement indicates the great potential of the detector to validate end-to-end workflows of online adaptive radiotherapy

On the orientation independence of the HYPERSCINT scintillation dosimetry research platform in a MR-linac environment.

The purpose of this work was to characterize the HYPERSCINT scintillation dosimetry research platform in a MR-linac environment, particularly with respect to its orientation. This study shows that the HYPERSCINT scintillation dosimetry platform can be used regardless of its orientation in a magnetic field environment. Together with its linearity to dose and dose-rate, the detector shows great promises for development of dosimetry solutions dedicated to the MR-Linac environment.
