Abstract
A detector for the image brightness which is present at the output screen of an x-ray image intensifier is formed by a combination of individual detector elements, the detector elements having different shapes and/or sizes. The detector elements in combination form a matrix which enables an optimum selection of a desired measurement field by selecting defined combinations of individual detector elements.
