Sagittal cross-sections showing MRI voxel intensity for patients with (a) almost entirely fat breast tissue (ACR I) and (b) scattered fibroglandular breast tissue (ACR II), with the corresponding cross-sections of the 3D numerical breast phantoms showing the dielectric constant at 6 GHz. The two phantoms in (c) and (d) (shown in color) were derived from (a) and (b) respectively, using the GMM-based piecewise-linear mapping scheme proposed in this paper. The two phantoms in (e) and (f) (shown in color) were derived from (a) and (b) using a uniform mapping scheme.
