Abstract
The paper describes a practically implemented method for correcting the geometrical aberrations introduced by a scanning device as a proposed stage of the computer radiography system qualification. The presence of geometrical distortions in the scanned images affects the metrological characteristics of the measurement methods and techniques that are using these systems. The method allows for correction of a systematic error obtained when scanning photostimulable phosphor detectors on the digital radiography devices. The main stages of method implementation include fabrication of the calibration sample, conducting reference instrumental measurements, comparing reference measurements with digital image processing results, and estimation and correcting the errors. During the period 2022 to 2024, the examination results for three scanning devices were analyzed. The use of the geometrical aberration correction method allows for minimization of distortions as well as estimation of quality and stability of the scanning devices
