We introduce a novel wave field reconstruction method which we used for analyzing 3D-multifrequency MRE brain data of 23 healthy volunteers providing viscoelastic parameter maps with a spatial resolution superior to former approaches. Individual parameter maps reflecting the magnitude of the complex modulus and the powerlaw exponent of the springpot model were normalized and averaged in order to obtain an atlas of the mechanical anatomy of the human brain.
