ABSTRACT:
In an image detection system having a CCD sensor, particularly for an x-ray examination apparatus, image read-out is substantially accelerated. This is achieved by discarding portions of the electronic image that is stored in the image storage-part of the CCD. Thus, only, portions of the image that contain relevant image information are converted into an electronic video signal.
