Clinical validation of myOSLchip: A beryllium oxide optically stimulated luminescent dosimeter (OSLD) system in radiotherapy dosimetry.

Abstract
In radiation oncology, inter-fractional dosimetry using optically stimulated luminescent detectors (OSLDs) ensures accurate plan delivery and patient safety. RadPro International GmbH's myOLSchip system, featuring a beryllium oxide (BeO) OSL dosimeter, reader, and eraser, was characterized and calibrated with a Varian Truebeam for in-vivo dosimetry following AAPM TG-191 guidelines. The BeO detectors demonstrated good dose linearity and repeatability across multiple exposures and erasure cycles, aligning with the manufacturer's stated accuracy and precision.
