DESCRIPTION
BS EN 62220-1-1:2015 - TC
This standard BS EN 62220-1-1:2015 - TC Tracked Changes. Medical electrical equipment. Characteristics of digital x-ray imaging devices is classified in these ICS categories:
- 11.040.50 Radiographic equipment
- necessary modifications have been applied as a consequence of taking into account IEC 61267:2005. This influences HVL values and SNRin2;
- the method for the determination of LAG EFFECTS now considers lag and ghosting compensation;
- as part of the MTF determination, the method of obtaining the final averaged MTF has been restricted (only averaging of the ESF is allowed);
- a description of (optionally) obtaining the diagonal (45°) MTF and NPS has been added.
