1. A method for producing a three-dimensional digital x-ray image by using digital x-ray images taken of an object from at least two different directions as input for a reconstruction algorithm, wherein, at least one of the images used as an input is a tomosynthetic slice image of a region of interest in the object of imaging, wherein the tomosynthetic slice image comprises a sharp image layer, and a blurred image layer and the reconstruction algorithm produces the three-dimensional digital x-ray image of the region of interest using both the sharp image layer and the blurred image layer.
