Calibration and equivalency analysis of image plate scanners

TLDR

The study proposes a universal calibration method for image plate scanners that can be applied to any system. The authors developed a protocol using radioisotope sources, cross‑calibrating scanner models, and deriving an empirical sensitivity relation to convert image‑plate dosages into physical units across arbitrary gain settings. The approach permits direct comparison of quantitative data between any facility and scanner.

Abstract

A universal procedure was developed to calibrate image plate scanners using radioisotope sources. Techniques to calibrate scanners and sources, as well as cross-calibrate scanner models, are described to convert image plate dosage into physical units. This allows for the direct comparison of quantitative data between any facility and scanner. An empirical relation was also derived to establish sensitivity response settings for arbitrary gain settings. In practice, these methods may be extended to any image plate scanning system.
