Abstract
A scattered-ray grid has a carrier with absorption elements arranged thereon in spaced rows which proceed essentially spoke-like relative to a grid center. Except for one or more rows which originate at the grid center, the individual rows of the scattered-ray grid, or of substantially identical grid sectors of the scattered-ray grid each originate from respectively different radii. The origin of each row is situated in an angle section, which is determined on the basis of at least two points lying on a circle, or an arc of circle, with a predetermined radius and which is divided in a predefined ratio for determining the position of the origin. The predetermined radius is incremented in a stepwise manner to define respective origins for all of the rows.
