Medical electrical equipment - Characteristics of digital X-ray imaging devices - Part 2-1: Determination of dual-energy subtraction efficiency - Detectors used for dual-energy radiographic imaging
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 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.
