WebOct 5, 2011 · The Bucky factor and selectivity increased in accordance with the increase in the grid ratio, which agreed with the report of Ishikawa et al. . Although a good grid is defined by the combination of a small Bucky factor and large selectivity, the larger the selectivity, the larger the Bucky factor, in general. WebWhat is bucky factor (aka grid conversion factor)? Determines what increase in mAs is needed to maintain film density. TF: Higher grid ratio means lower bucky factor. False. Why does mAs have to be increased when the bucky factor is increased? The grid is taking away density.
