Abstract: A marking grid is provided for use in radiographic imaging, and a method is provided for manufacturing the marking grid. The marking grid is comprised of a radiolucent substrate with a pressure sensitive adhesive on one side, a plurality of parallel strips of radiopaque material fixed to the substrate on the side opposite the pressure sensitive adhesive, and apertures in the substrate between the parallel strips of radiopaque material. The substrate is provided on a releasable backing with a plurality of holes longitudinally spaced relative to each other, which can be used to register the position of the substrate in the equipment used to produce the marking grids.
