Abstract

1 Scope This document describes the performance metrics associated with dual-energy imaging capable digital X- ray imaging devices meant for medical applications and specifies the methods for their determination. These metrics can be used to analyse tissue-subtracted images and to evaluate dose performance, noise characteristics, and tissue-subtraction efficacy of digital X- ray imaging devices . The described methods indicate the procedures to obtain multi-spectral primary data and to compute their derived tissue-subtracted images . The intended users of this document are manufacturers and well-equipped test laboratories. This document is restricted to digital X- ray imaging devices that are used for single or multiple exposure dual-energy radiographic imaging based on, for example, CR systems, direct and indirect flat panel-detector based systems. This document excludes and is not applicable to:

— digital X- ray imaging devices intended to ...
