Medical electrical equipment - Characteristics of digital X-ray imaging devices - Part 1: Determination of the detective quantum efficiency
Specifies the method for the determination of the detective quantum efficiency (DQE) of digital X-ray imaging devices as a function of exposure and of spatial frequency for the working conditions in the range of the medical application as specified by the manufacturer. Is applicable to projection digital X-ray imaging devices producing images in digital format that are used for medical diagnosis. It is restricted to digital X-ray imaging devices that are used for radiographic imaging, such as CR systems, selenium-based systems, flat panel detectors, optically coupled CCD detectors, and digital X-ray image intensifiers used for single exposures.

Foreword
The text of document 62B/493/FDIS, future edition 1 of IEC 62220-1, 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 on 2003-12-01.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2004-09-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2006-12-01
In this standard, terms printed in SMALL CAPITALS are used as defined in IEC 60788, in Clause 3 of this
standard or other IEC publications referenced in Annex B. 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
