An X-ray examination apparatus with a locally divided auxiliary detector

摘要

Incorporated in an X-ray examination apparatus is a detector array 32 for the detection of the image-carrying beam 10, which array is set up in such a manner that image information from substantially the entire output screen of an X-ray image-intensifier tube incorporated in the apparatus can be detected. The detector array is used for brightness control and for adaptation of the quantities influencing the image quality, in which process use can be made of a measured field which can be programmed to be selected, to be positioned and to be set and in which process spatial image information can also be used by the matrix form of the detector.
