X-ray imaging plate performance investigation based on a Monte Carlo simulation tool

Computed radiography (CR) based on imaging plate (IP) technology represents a potential replacement technique for traditional film-based industrial radiography. For investigating the IP performance especially at high energies, a Monte Carlo simulation tool based on PENELOPE has been developed. This tool tracks separately direct and secondary radiations, and monitors the behavior of different particles. The simulation output provides 3D distribution of deposited energy in IP and evaluation of radiation spectrum propagation allowing us to visualize the behavior of different particles and the influence of different elements. A detailed analysis, on the spectral and spatial responses of IP at different energies up to MeV, has been performed. •A Monte Carlo tool for imaging plate (IP) performance investigation is presented.•The tool outputs 3D maps of energy deposition in IP due to different signals.•The tool also provides the transmitted spectra along the radiation propagation.•An industrial imaging case is simulated with the presented tool.•A detailed analysis, on the spectral and spatial responses of IP, is presented.
