Section: claims

1. A method for producing absorptione elements for a slit radiography assembly, which comprises: forming a template of a cross-sectional shape for said absorption elements by defining at least two cut lines between two equidistant lines of absorption thickness of absorption material, said cut lines being non perpendicularly transverse to said equidistant lines; by defining two edge regions with a boundary line on either side of each cut line, each of said edge regions being bounded by said cut lines, said boundary line extending transversely to said equidistant lines and a part of at least one of said equidistant lines; and by moving said edge regions on either side of each said cut lines a distance in an opposite direction along said boundary lines to produce a gap at a position of each of said cut lines thereby forming said cross-sectional shape between respective gaps; and  forming an absorption element of said cross-sectional shape from said template. 2. The method for producing absorption elements as defined in claim 1 wherein straight shoulders produced by movement at the position of said boundary lines are chamfered by displacing a projecting angular section near one equidistant line to an oppositely situated angular section near the other equidistant line. 3. The method for producing absorption elements as defined in claim 1 wherein at least one of said cut lines is kinked having a first section extending between an intersection thereof with one of said equidistant lines and a point of inflection and having a second section extending between said point of inflection and a second of said equidistant lines and wherein said boundary line is drawn transversely through said point of inflection and wherein a region formed by said boundary line, said first section and a part of a first of said equidistant lines is moved in a first direction transversely to said equidistant lines and wherein a region formed by said boundary line, said second section and a second of said equidistant lines is moved in said opposite direction and the thus-produced projecting corners at a position of said intersection of said boundary line with said equidistant lines is filled by triangular sections removed at the level of the original point of inflection.
