Basic Spatial Resolution (SRb)
The Basic Spatial Resolution results from measurement of the image un-sharpness with a duplex wire IQI (Image Quality Indicator). The Basic Spatial Resolution indicates the smallest geometric detail resolved in a radiographic image.
A differentiation is made between:
- Basic Spatial Resolution of the detector (SRbdetector):
The duplex wire IQI is placed directly on the detector surface. - Basic Spatial Resolution of the radiographic image (SRbimage):
The duplex wire IQI is placed on the test object surface facing the source.
