Bucky factor

The Bucky factor or grid exposure factor of an anti-scatter grid is the ratio of the mAs used with the grid present to the mAs used without the grid, to provide the same quality image for a specific kVp.

Hence, the Bucky factor reflects the increased radiation dose required from anti-scatter grid use, as any increase in mAs proportionally increases dose.

The Bucky factor changes with:

  • change in kVp
  • change in grid ratio
