Independent verification of vendor‐issued dosimetric data for ¹⁰⁶ Ru brachytherapy using diode detectors with traceability to external beam standards for absorbed dose to water

We present a novel, comprehensive methodology for independent and traceable absolute dosimetry of ¹⁰⁶Ru applicators. By combining a dedicated water phantom setup with diode detectors calibrated against external beam standards and MC-derived correction factors, this framework empowers clinical users to perform robust verification measurements, filling a critical gap in the quality assurance of ocular brachytherapy.
