ABSTRACT:
In order during an x-ray examination, despite a variable foreign magnetic field at the location of an x-ray tube to still enable x-ray images with image sections giving the same coverage to be generated, there is provision in accordance with the invention to compensate for the previously determined change to the foreign magnetic field at the location of the x-ray tube by a correspondingly controlled opposing magnetic field; Advantageously at least one compensating magnet is provided for this purpose which can be assigned to the x-ray tube and is controllable by a processing unit depending on this change.
