Study Notes
Spatial Resolution
- Spatial resolution describes the ability to distinguish separate objects.
- Factors influencing spatial resolution include pixel size, focal spot size, detector size, image reconstruction filters, and sampling frequency.
- Smaller pixel sizes improve the ability to differentiate closely spaced objects.
- Larger pixel sizes result in blurred images, making it harder to distinguish nearby objects.
- Spatial resolution is measured in line pairs per millimeter (lp/mm).
