000008758 520__ $$2eng$$aFollowing previous studies employing X-ray physics and continuum micromechanics in order to retrieve voxel-specific elastic properties from Computed Tomographs (CT) (Hellmich et al., 2008), we here present an updated and improved approach applied to in-vivo images of vertebrae of a young patient. This approach concerns both elasticity and strength, and therefore promises considerable impact on patientindividual, image-based fracture risk assessment. This is done for the described voxel-specific heterogeneous case, as well as for vascular porosities averaged over the trabecular core. Homogeneous simulations obviously underestimate the fracture risk in the presently studies case.
