First Experimental Demonstration of Time-Resolved Plastic Scintillation Dosimetry On An MR-Linac

To maximize healthy tissue sparing in the presence of respiration, we previously developed MRI-guided MLC tracking for the 1.5T Unity MR-linac (Elekta AB, SWE). Dosimetric analyses were performed using film dosimetry.

Comparison Between the HYPERSCINT RP200 Scintillation Detector and Other Small Field Detectors for 10MV FFF SRS Beam Modelling On a VersaHD Linear Accelerator

Plastic scintillation detectors (PSDs) have advantageous dosimetric properties, including small size and energy independence, which make them ideal candidates for small field dosimetry.

Patient Specific QA for External Beam Radiotherapy Using the HYPERSCINT Plastic Scintillation Detector

Plastic scintillation detectors (PSDs) have interesting dosimetric properties, including small size and energy independence. These advantages make them well suited for VMAT patient-specific QA, either alone or in conjunction with a detector matrix. This work aims to determine if the HYPERSCINT scintillation dosimetry research platform (Medscint inc., Quebec city, Canada) can replace the classic ion chamber in a clinical patient-specific QA workflow.

Characterization of the Hyperscint Dosimetry System for Real-Time Dosimetry Measurements with the Varian TrueBeamLinac

Plastic scintillator/optical fibre dosimetry systems are advantageous due to their near water equivalence, waterproof construction, linear dose response, and good spatial resolution due to their small size. The nanosecond decay times of plastic scintillators enable the possibility of real-time dosimetry. We tested the new Hyperscint?? fibre detector system to determine if, in addition to the expected dose and field size responses, this system can provide real-time dose information.

On the nature of the light produced within PMMA optical light guides in scintillation fiber-optic dosimetry

The goal of this study was to evaluate the nature of the stem effect light produced within an optical fiber, to quantify its composition, and to evaluate the efficiency of the chromatic technique to remove the stem effect.
