ABSTRACT:
The invention relates to a method for creating scatter-corrected mass density image in dual energy X-ray absorptiometry. The mass density image is created using additional information provided by attenuation images at different energy levels in an inhomogeneous correction image area. A multi-dimensional mass density is found that is consistent for a plurality of the attenuation images by inverting a primary radiation function. A scatter fraction is determined on the basis of the multi-dimensional mass density.
