X-ray diagnostic apparatus comprising an X-ray image intensifier and a detector for its output screen image brightness

摘要

The aim to is to produce a detector (8) for the output screen image brightness of an X-ray image intensifier having a matrix of detector elements (8a etc.), in which an optimal selection of the desired measuring field is possible by selection of specific combinations of detector elements (8a etc.). …??For this purpose, the detector elements (8a etc.) have different shapes and/or sizes.
