Abstract: The present invention relates to a method for generating a bone density value. The method comprises the steps of: generating digital image data depending upon an X-ray image corresponding to at least a part of the bone; transmitting a digital image data signal comprising the digital image data; and processing said digital image data signal. The processing step comprises the sub steps of: generating a trabeculae model depending upon said processed digital image data signal; generating at least one geometrical figure depending upon the generated trabeculae model, wherein the generated geometrical figure is provided essentially within a space at least partly defined by centre lines of the generated trabeculae; calculating the bone density value depending upon the at least one generated geometrical figure.
