DIN Standards Committee Radiology

Overview

This document has been prepared by Subcommittee SC 62B "Medical imaging equipment, software, and systems" of the International Electrotechnical Commission (IEC). The responsible national standardization committee is Working Committee NA 080-00-06 AA "Bildgebende Systeme" ("Image acquisition systems") at DIN Standards Committee Radiology (NAR). 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 be used in mammography or in dental RADIOGRAPHY; – slot scanning DIGITAL X-RAY IMAGING DEVICES; – COMPUTED TOMOGRAPHY or CONE-BEAM COMPUTED TOMOGRAPHY; – photon-energy discriminating devices such as photon counting X-RAY IMAGING DEVICES; – devices for dynamic imaging (where series of images are acquired, as in fluoroscopy or cardiac imaging). – DIGITAL X-RAY IMAGING DEVICES intended to be used with RADIOTHERAPY beams.
