Abstract
X-ray images are generated from a CCD image sensor having an image section and at least one storage section by performing a first X-ray exposure during a first time interval (T.sub.1) which is shorter than the read-out period (T.sub.r) of an image stored in the storage section of the CCD image sensor (7) to form a first image in the image section, transferring the first image from the image section to the storage section after expiration of the first time interval (T.sub.1), performing a second X-ray exposure directly after or a small interval in time after the first X-ray exposure during a second time interval (T.sub.2) which is short in comparison with the read-out period (T.sub.r) to form a second image in the image section, reading out the first image from the storage section and writing the first image into a further memory, transferring the second image from the image section to the storage section after reading out the first image, and reading out the second image and summing it with the first image written in the further memory.
