An apparatus for reducing radiation scatter in an imaging system 100 having an operational slot 121 for receiving an anti-scatter grid. The apparatus includes an imaging system component having at least one storage slot 123 formed therein for selectively storing an anti-scatter grid when the grid is not in the operational slot 121 of the imaging system 100. The apparatus further includes an operational slot sensor configured to detect the presence of an anti-scatter grid and/or an imaging property of a grid in the operational slot. The system 100 allows an operator to select an appropriate anti-scatter grid for use in the imaging system from one or more anti-scatter grids that are located within the operational and/or storage slots 121, 123 of the imaging system 100.
