Grid Frequency Quiz

Lower frequency requires more X-ray photons to produce an image

Higher frequency results in finer grid lines and less interference with the image (correct)

Lower frequency grids are recommended for mobile radiography

Higher frequency results in a lower dose for the patient

Grid ratio has no effect on scatter radiation

The higher the ratio, the more scatter radiation is produced

The higher the ratio, the more scatter radiation is absorbed (correct)

The lower the ratio, the more scatter radiation is absorbed

Parallel grids are more effective at reducing scatter radiation

Focused grids are less critical to beam centering

Parallel grids are less critical to beam centering, but should not be used at distances less than 48 inches (correct)

Focused grids should not be used at distances less than 48 inches
