Claim One:
1. A method of forming X-ray images, in which a charge pattern which corresponds to the X-ray intensity is generated on the surface of a photoconductor, which charge pattern is line-wise scanned by means of a number of probes which detect the charge in respective scanning zones of the photoconductor which adjoin one another and which comprise several lines, said probes supplying digital image values (B.sub.n (x,y)) of the X-ray image which are dependent on the charge, comprising the following steps: a) formation of correction values (K.sub.n (x,y.sub.o)) for the pixels of the image lines (y.sub.o) at the edges of the scanning zones of the probes, the absolute value and sign of the correction values being such that the corrected image values (B.sub.kn (x,y.sub.o)) of the individual probes, resulting from the superposition of the correction values and the image values (B.sub.n (x,y.sub.o)), correspond to the corrected image values of the respective neighbouring probes; b) forming of intermediate values (Z.sub.n (x,y)) for the image lines (y) situated between the edges of the scanning zones of the probes by interpolation of the correction values (K.sub.n (x,y.sub.o); K.sub.n (x,y.sub.u)) associated with the same probe; and c) superposing the correction values, or the intermediate values and the image values in order to produce corrected image values for the image lines of the scanning zones.
