Image Quality Indicator

Detectability of details of a radiographic film essentially depends on the image quality of the radiographic film.

The different image quality indicators (IQI) and their application for determination of the image quality number are described in standards such as EN ISO 19232 "Non-destructive testing. Image quality of radiographs. "

IQIs are delivered together with a declaration of conformity (e.g. acc. to ISO/IEC-Guide 22)

IQI according to EN ISO 19232 - double wire penetrameter

Determination of image unsharpness

13 pairs of wires of decreasing wire diameter (1D - 13D)
1D - 3D consist of tungsten, the others are made of platinum
Evaluation of X-ray films with magnifying glass (max. magnification 4x)
Image unsharpness "U" is determined by the wire pair whose two wires can be recognised just disconnected
Application in connection with IQI wire penetrameter or step/hole IQI is recommended

Element no.	Image unsharpness "U"	Wire Diameter = wire distance
13D	0.10	0.050 mm
