Abstract
The invention relates to an arrangement of sensor elements in which the sensor elements are arranged to detect electromagnetic radiation, such as X-rays or light, and to generate in response thereto a charge signal which corresponds to the radiation intensity. Furthermore, a sensor element includes means which enable determination of the incident radiation dose. The sensor elements in the arrangement form groups so that the outputs of all sensor elements of a group are coupled and the sensor elements of a group are preferably arranged so as to neighbor one another. This on the one hand enables determination of the dose in these zones while on the other hand images of lower resolution can be formed simply by combining output signals of a plurality of sensor elements. An arrangement of this kind can be used, for example, in an X-ray diagnostic device or in an optical image acquisition system.
