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

IEC 62220-2-1:2023 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.

Appareils électromédicaux - Caractéristiques des dispositifs d’imagerie à rayonnement X - Partie 2-1: Détermination de l’efficacité de soustraction à double énergie - Détecteurs utilisés en imagerie radiographique à double énergie

L'IEC 62220-2-1:2023 décrit les mesures normalisées de performances associées aux DISPOSITIFS D’IMAGERIE NUMERIQUE A RAYONNEMENT X capables d’IMAGERIE A DOUBLE ENERGIE destinés à des applications médicales, et spécifie leur méthode de détermination. Ces mesures normalisées peuvent être utilisées pour analyser les IMAGES SOUSTRAITES DES TISSUS et pour évaluer les performances liées à la dose, les caractéristiques sonores et les performances de soustraction des tissus des DISPOSITIFS D’IMAGERIE NUMERIQUE A RAYONNEMENT X. Les méthodes décrites indiquent les procédures permettant d’obtenir des DONNEES PRIMAIRES MULTISPECTRALES et de calculer les IMAGES SOUSTRAITES DES TISSUS qui leur sont dérivées. Les utilisateurs prévus du présent document sont les FABRICANTS et les laboratoires d'essai aux équipements modernes. Le présent document est limité aux DISPOSITIFS D’IMAGERIE NUMERIQUE A RAYONNEMENT X qui sont utilisés dans l’imagerie radiographique à double énergie à exposition unique ou multiple fondés, par exemple, sur les systèmes CR et les systèmes à base de détecteur à panneau plat direct ou indirect. Le présent document exclut et ne s’applique pas: – aux DISPOSITIFS D’IMAGERIE NUMERIQUE A RAYONNEMENT X destinés à être utilisés en mammographie ou en RADIOGRAPHIE dentaire; – aux DISPOSITIFS D’IMAGERIE NUMERIQUE A RAYONNEMENT X à balayage de fente; – à la TOMODENSITOMETRIE ou à la TOMODENSITOMETRIE A FAISCEAU CONIQUE; – aux dispositifs de discrimination en énergie de photon, tels que les DISPOSITIFS D’IMAGERIE A RAYONNEMENT X à comptage de photon; – aux dispositifs d’imagerie dynamique (où des ensembles d’images sont acquis, comme en radioscopie ou en imagerie cardiaque). – aux DISPOSITIFS D’IMAGERIE NUMERIQUE A RAYONNEMENT X destinés à être utilisés avec des faisceaux de RADIOTHERAPIE.
