1. A method for creating a synthetic mammogram based upon a dual energy tomosynthesis recording of an examination region, the method comprising:
making a low energy tomosynthesis recording with a first X-ray energy spectrum;
making a high energy tomosynthesis recording with a second X-ray energy spectrum of relatively higher energy compared with the first X-ray energy spectrum, wherein the examination region includes a contrast medium distribution;
determining a subtraction volume based upon the high energy tomosynthesis recording and the low energy tomosynthesis recording;
generating a three-dimensional probability map with a weighting factor per voxel based upon the subtraction volume; and
creating a synthetic mammogram based upon the three-dimensional probability map.
