ABSTRACT:
The invention relates to a method of generating a layer image from a plurality of single images, the image processing errors which locally occur in the single images being substantially eliminated in the layer image. To this end, the image values for the individual layer image points are formed by that image value of the image points geometrically situated with the layer image point which corresponds to the next to the lowest absorption value.
