The performance characteristics of prototype grids constructed with 0.1-mm-thick Ta strips were investigated. Significant improvement in scatter cleanup was noted in comparison to commercially manufactured grids, which are constructed with 0.04-0.05-mm-thick Pb strips. Highly efficient scatter rejection, approaching that of slit radiography techniques, may be possible using crossed grids constructed with 0.1-mm Ta strips. By constructing a grid from a crossed pair of linear grids and moving these grids at right angles to each other, grid lines can be eliminated from crossed grid images.
