Description
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 first edition cancels and replaces NBN EN 62220-1.
It constitutes a technical revision and assures a better alignment with the other parts of the IEC 62220 series. The main changes are as follows:
- 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.
