  X-ray image: Madonna with the infant Jesus

  Information:
In the past historical paintings have sometimes been painted over by other artists. The motives for this procedure were different: Some artists have not been able to afford new canvas. But also, old paintings have often been painted over in order to manufacture fakes on chronological authentic canvas. Due to the varying ingredients of the old and the new colours, x-ray technology makes it possible to find out, whether there is an older painting behind the visible one. As paintings are in general much bigger than x-ray films, the x-raying of paintings with conventional methods means considerable effort. This effort can be reduced to a minimum by the use of NTB's x-ray cameras.
