<prompt> Bucky diaphragm?Reduces scattered radiationReduces response timeDecreases long wavelength raysDecreases kVp and mA requirement  <response>: Potter Bucky grid is a type of moving grid. These devices reduce the amount of scattered radiation reaching the film while still allowing the patterns containing the primary beams to reach the film.The image of radiolucent grid lines on the film can be deleted by moving the grid perpendicular to the direction of grid lines, this has the effect of blurring out the radiolucent line and allowing a more uniform exposure. This movement doesnt interfere with absorption of scattered photons.
