Simulating radiographic inspections with imaging plates

Abstract

Abstract. Computed Radiography (CR) based on photostimulable imaging plates (IP) is a potential replacement technique for traditional silver film radiography. For the inspections of components with high wall thicknesses requiring higher energy sources, however, imaging plate performance suffers from a spectral response which is low for the higher energies and high in the energy range where scattered radiation is typically observed. For these applications, care must be taken to apply appropriate filtering. Simulation tools are expected to be helpful in determining optimal operating conditions. We present a computer model which combines deterministic and Monte Carlo methods to simulate the imaging chain, focusing in particular on the scanner model.

Optically Stimulated Luminescence Phosphors: Principles, Applications, and Prospects

“…The physical characteristics of the OSL phosphor imaging plates (IPs) have great effect in the determination of the image quality. [ 260–267 ] As shown in Figure , in the workflow of CR, an optical storage IP (fabricated using OSL phosphors) is exposed in a light‐tight cassette as in screen/film radiography. After the exposure of X‐ray and identification of patient, the cassette is put in a scanner for information read‐out.…”
