Abstract
A device and a process for producing tomograms by means of an X-ray diagnostic device which has a C-frame-like mount (7) on which a radiation transmitter (5) and a planar detector as radiation receiver (6) are arranged at opposite ends facing each other. Various signals stored in memory (17, 18, 19, 27) are used by a signal processing device (4) in the calculation of processed image signals. These signals include signals (I.sub.P) relating to the central point of rotation (31) for the scanning operation, and signals (.DELTA.S, .DELTA.U) for correction geometric distortions and/or vignetting effects and/or the film-focus distance.
