Abstract
Because of the unique characteristics of imaging plates, computed radiography (cRT) enables the development of new radiographic techniques that were not possible with conventional film radiography, including material characterization. In this case, achieving maximum radiographic image quality is imperative which implies that every parameter of the cRT workflow must be controlled. The paper presents an analysis of the scanning parameter influence on the characterization of the cell structure of expanded polystyrene (PS-E). For this purpose, an experiment was conducted varying three main scanning parameters: resolution (Res), laser power (LP) and photomultiplier tube gain (PMT). In order to determine the significance of each scanning parameter for the radiographic image quality, a parameter called „worthiness“ was introduced. Also, using a mathematical model developed on the basis of the experiment, a methodology for the selection of scanning parameters for the cRT of PS-E of different compressive strength is proposed.
