A grid assembly for use with an imaging cassette. The grid assembly includes an anti-scatter grid having a length and opposing first and second ends; first and second transport members disposed proximate the first and second ends, respectively, of the grid; at least one first roller disposed at the first end of the grid; at least one second roller disposed at the second end of the grid; and a pair of support members disposed substantially perpendicular to the length and proximate the opposing ends of the grid in spaced relationship to form a slot having an opening proximate one side of the grid adapted to removably slidably receive the imaging cassette adjacent the grid.
