Scattered-ray grid for screening X-ray detector against a scattering radiation, comprises scattered-ray grid lamellas formed as screening device for electrical and/or magnetic interference fields and coated by ferromagnetic material

摘要

The scattered-ray grid (1) for screening X-ray detector against a scattering radiation, comprises scattered-ray grid lamellas formed as screening device for electrical and/or magnetic interference fields and partially coated by a ferromagnetic material with high permeability. Each lamella is formed from a hot metal layer and a layer of ferromagnetic materials. Lamellas are formed from alloy or mixture, which has hot metal and ferromagnetic material. An independent claim is included for X-ray detector with a scattered-ray grid.
