  • Method of producing an X-ray image by means of a photoconductor, and device for performing the method
    Patent number: 4939759
    Abstract: A method is disclosed for producing a X-ray image by a photoconductor which converts X-rays into a charge pattern and which is uniformly charged prior to the X-ray exposure and is discharged during the X-ray exposure as a function of the intensity of the X-rays, the surface of the photoconductor being scanned to measure the charge density, for each pixel point there being formed an image value which is dependent on the discharge at the relevant pixel whereby dot-shaped artefacts in the X-ray image may appear.
