Abstract
An exemplary embodiment includes a number of x-ray soures which are capable of being individually switched on in succession by means of a control generator, a patient support, an x-ray image intensifier which is surrounded by deflection coils which are connected with a deflection device, connected to the control generator, for the synchronous movement of the electron image in the x-ray image intensifier, a video camera which is aligned with the outlet fluorescent screen of the x-ray image intensifier, an image storage and a monitor, wherein the image storage is so designed that at least two groups of different individual images, superimposed, respectively, are capable of being stored. The control inputs of the image storage for the purpose of group-wise storage, are connected with the control generator. Associated with the image storage is a comparator which is so designed that it compares mutually corresponding image point data contained in the image storage and supplies only those particular image point data to the monitor which are in conformity.
