Bucky factors
The Bucky factor is the ratio of radiation on the anti-scatter grid to the transmitted radiation. 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 WebJan 1, 1999 · MATERIALS AND METHODS: Contrast improvement factors and Bucky factors were determined for four mammographic units as a function of x-ray tube potential (25, 30, and 35 kVp), phantom thickness (2, 4, and 8 cm) and, on one unit, three target-filter combinations. Three units used a linear grid; one, a cellular grid.

WebApr 17, 2024 · Typical Bucky factors for grids used in abdominal X-ray imaging are between 3 and 8. The Bucky factor has more relevance in screen-film radiography than digital radiography. This is because screen-film cassettes have a fairly narrow dynamic range and the loss of signals by the use of grids would result in an underexposed film, … Web1 a mercantile agent.
