Abstract

The invention relates to an anti-scatter grid for the absorption of X-rays, wherein the wall elements (3) of the grid consist of a thermoplastic (7) with heavy metal particles (8) embedded therein. By using such a mixture, it is possible to produce the wall elements by injection molding, whereby even very finely and complicatedly shaped, in particular two-dimensional, grids may be produced in cost-effective manner.
