YY/T 0590.3-2011Medical electrical equipment—Characteristics of digital X-ray imaging devices - Part 1-3: Determination of the detective quantum efficiency—Detectors used in dynamic imaging (English PDF)

1 Scope

YY/T 0590 This section specifies the use under medical conditions specified by the manufacturer working to release the kinetic energy of air ratio and spatial frequency

Determination of the detective quantum efficiency of digital X-ray imaging apparatus function. Expected users of this section is the manufacturer and well-equipped test laboratory.

This section limits for dynamic imaging of digital X-ray imaging apparatus, such as, but not limited to, directly or indirectly, based on flat panel detector system.

This should not be part of YY/T 0590 is applied based on the X-ray image intensifier digital system.

Note 1. The reason why not is based on the phenomenon of low frequency drop and vignetting and geometric distortion phenomenon appears to consider in these devices, these phenomena may be serious

Limit measuring method described in this section applicability.

YY/T 0590 This section does not apply to.

--- Use of digital X-ray imaging apparatus mammography or dental photography;

--- Computer tomography equipment; and

--- Patient scan imaging X-ray systems;

Note 2. Does not include the above-described means, because they contain a lot different than for dynamic imaging very important parameters (for example, radiation quality, geometry, time

Dependence, etc.). Some of these parameters in other parts (YY/T 0590.1 and YY/T 0590.2) has been specified.
