Exposing object e.g. patient chest, illustrating method, involves arranging scattered radiation raster between exposing object and x-ray detector, and moving raster away from path of radiation of x-ray depending on thickness of object

摘要

The method involves reducing scattered radiation portion of a x-ray radiation (8) that penetrates an exposing object, using a x-ray unit with a scattered radiation raster (4). The scattered radiation raster is arranged between the object and an x-ray detector (5) which is arranged behind the object. The raster is moved away from a path of the radiation of the x-ray depending on the thickness of the object. An independent claim is also included for an x-ray unit for illustrating an exposing object such as patient chest.
