Medical electrical equipment - Characteristics of digital X-ray imaging devices - Part 1-2: Determination of the detective quantum efficiency - Detectors used in mammography

Specifies the method for the determination of the detective quantum efficiency (DQE) of digital X-ray imaging devices as a function of air kerma and of spatial frequency for the working conditions in the range of the medical application as specified by the manufacturer. The intended users of this part of IEC 62220 are manufacturers and well equipped test laboratories. This Part 1-2 is restricted to digital X-ray imaging devices that are used for mammographic imaging such as but not exclusively, CR systems, direct and indirect flat panel detector based systems, scanning systems (CCD based or photon-counting). This part of IEC 62220 is not applicable to - digital X-ray imaging devices intended to be used in general radiography or in dental radiography; - computed tomography; and - devices for dynamic imaging (where series of images are acquired, as in fluoroscopic or cardiac imaging).

Appareils électromédicaux - Caractéristiques des dispositifs d'imagerie numérique à rayonnement X - Partie 1-2: Détermination de l'efficacité quantique de détection - Détecteurs utilisés en mammographie

Spécifie la méthode de la détermination de l'efficacite quantique de détection (EQD) des dispositifs d'imagerie numérique à rayons X en fonction du kerma dans l'air et de la fréquence spatiale pour les conditions de fonctionnement dans la gamme des applications médicales, suivant les spécifications du fabricant. Les utilisateurs prévus de la présente partie de la CEI 62220 sont les fabricants et les laboratoires d'essai bien équipés. Cette Partie 1-2 est limitée aux dispositifs d'imagerie numérique à rayonnement X utilisés dans l'imagerie mammaire, tels que, mais pas exclusivement, les systèmes à écrans photo stimulables (connus sous la désignation de 'Computer Tomography', CR), les systèmes à base de détecteur à panneau plat direct ou indirect, les systèmes de balayage (à base de dispositif à transfert de charge (CCD en anglais) ou à comptage de photons). La présente partie de la CEI 62220 n'est pas applicable: - aux dispositifs d'imagerie numérique à rayonnement X destinés à être utilisés en radiographie générale ou en radiographie dentaire; - à la tomodensitométrie; et - aux dispositifs d'imagerie dynamique (où des ensembles d'images sont acquis, comme dans l'imagerie radioscopique ou cardiaque).

Foreword
The text of document 62B/649/FDIS, future edition 1 of IEC 62220-1-2, prepared by SC 62B, Diagnostic
imaging equipment, of IEC TC 62, Electrical equipment in medical practice, was submitted to the
IEC-CENELEC parallel vote and was approved by CENELEC as EN 62220-1-2 on 2007-09-01.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
(dop) 2008-06-01
national standard or by endorsement
– latest date by which the national standards conflicting

In this standard, terms printed in SMALL CAPITALS are used as defined in IEC/TR 60788, in Clause 3 of this
standard or other IEC publications referenced in the Index of defined terms. Where a defined term is used
as a qualifier in another defined or undefined term it is not printed in SMALL CAPITALS, unless the concept
thus qualified is defined or recognized as a “derived term without definition”.
NOTE  Attention is drawn to the fact that, in cases where the concept addressed is not strongly confined to the definition given in
one of the publications listed above, a corresponding term is printed in lower-case letters.
In this standard, certain terms that are not printed in SMALL CAPITALS have particular meanings, as follows:
– "shall" indicates a requirement that is mandatory for compliance;
– "should" indicates a strong recommendation that is not mandatory
