ABSTRACT:
A method of generating layer images from a number of single-shadow images and a device for performing this method. The absorption values associated with the image points of the single-shadow images are stored in a memory. The image value of the layer-image point is formed from the lowest absorption values associated with this layer-image point. Structures or artefacts which are situated outside the layer being imaged can thus be eliminated from the image.
