A method of manufacture of an anti-scatter grod structure for protectively housing a grid therein, the steps of cutting a solid upper and lower plates to a given size lightly larger than the cassette to be housed by the grid structure, forming a generally U-shaped frame structure with interior vertically spaced ledges with an upper ledge being sized for supporting the lower plate and with a lower ledge being vertically spaced therefrom and sized for under lapping the lower plate and supporting a cassette in assembly with the frame, securing the lower plate in assembly with the frame while engaged with the upper ledge, mounting a grid in centered relation on the lower plate and limiting the extent of shifting movement of the grid relative to the lower plate, positioning a solid upper plate over the grid in parallel relation to the lower plate, and securing the solid upper plate to the U-shaped frame structure in unitary assembly. An X-ray grid structure for assembly with a cassette comprising a rectangular, flat panel comprised of a polycarbonate material and having an interior closed panel pocket, an X-ray grid protectively encased in the interior panel pocket of the flat panel so as to be protected therein against impact forces when applied to the panel, a frame around three side edges of the panel, the frame being comprised of a UHMW plastic for cushioning impacts, means securing the frame to the flat panel along the three side edges but with the means being spaced from the grid at its outer peripheral edges, and a groove in the frame forming a cassette pocket beneath one flat side of the panel for a cassette to be slidably received in the cassette pocket to thereby form a grid cassette when assembled.
