Spatial resolution refers to the ability of an imaging modality to differentiate two adjacent structures as being distinct from one another. Other related terms include definition or visibility of detail.
Spatial resolution is expressed in line pairs per mm (lp mm).
The absence of spatial resolution in an image may be referred to as blur.
When optimized, screen film systems have excellent spatial resolution, whereas electronic detectors are limited by pixel size.
