Sagittal cross-sections showing MRI voxel intensity for patients with (a) heterogeneously dense breast tissue (ACR III), and (b) extremely dense breast tissue (ACR IV), with the corresponding cross-sections of the 3D numerical breast phantoms showing the dielectric constant at 6 GHz. The 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.
