ABSTRACT:
The so-called memory effect occurring in a device for forming X-ray images by means of an X-ray image converter which includes a photoconductor for converting the X-rays into a charge pattern can be reduced by means of a trapping layer which is provided on at least one of the two sides of the photoconductor and reduces the current of charge carriers injected into the photoconductor from this side.
