Overview

An anti scatter grid reduces scattered radiation reaching the detector to improve image contrast. Grids are used for thicker body parts and higher kV exposures. Proper alignment prevents grid cutoff artifacts.

Grid Types

Linear crossed and focused grids offer different scatter rejection and alignment characteristics. Grid ratio and frequency influence scatter suppression and exposure requirements. Selection depends on clinical application and detector type.

Care and Handling

Grids must be handled carefully to avoid bending and damage. Regular inspection for warping and lead strip damage prevents artifacts. Cleaning protocols maintain grid integrity without damaging the structure.

Integration with Digital Detectors

Digital detectors may require specific grid configurations to avoid moire patterns. Grid removal or software based scatter correction are options for certain workflows. Vendor guidance ensures optimal pairing of grid and detector.
