ABSTRACT:
A method for manufacturing an anti-scatter grid including arranging a plurality of elongated metal ribbons of radio-opaque material so that each ribbon is substantially straight and lies in a plane that passes through a focal point of the grid, and placing the elongated ribbons under tension. A first sheet of radioluscent material is secured to top edges of the ribbons, and a second sheet of radioluscent material is secured to bottom edges of the ribbons. The ribbons are arranged such that the first and second radioluscent sheets are substantially parallel. Then the tension is removed from the ribbons.
