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.
