Technical note: Characterization of a multi-point scintillation dosimetry research platform for a low-field MR-Linac.

Background: MRI-guided radiation therapy (MRgRT) requires unique quality assurance equipment to address MR-compatibility needs, minimize electron return effect, handle complex dose distributions, and evaluate real-time dosimetry for gating. Plastic scintillation detectors (PSDs) are an attractive option to address these needs.

Purpose: To perform a comprehensive characterization of a multi-probe PSD system in a low-field 0.
