A method for producing an antiscatter grid or collimator

摘要

The present invention relates to a process for producing an antiscatter grid or collimator, for which any kind of the transparent regions (5) and impermeable regions (6) of predetermined geometry. In the method, the geometry of the transmissive (5) and the nontransmissive regions (6) of the antiscatter grid or collimator is initially set. On the basis of this geometry, a base (16) in accordance with the possibly differing by a particular layer thickness geometry of the transmissive regions (5) or the nontransmissive regions (6) by means of a rapid prototyping technique through layer-wise solidification of a structural material under the action of radiation is built up. On the basis of this base body (16) is finally the antiscatter grid or collimator is completed. Dollars a the present process makes it possible to the simple and cost effective production of scattered radiation grids or collimators with very filigree absorption structures. This makes possible a better utilization of the primary radiation in the case of the taking of an image.
