Linear piecewise mapping between the voxel intensities and the corresponding dielectric property curve for a histogram of an exam where the fat tissue is predominant over the fibroglandular tissue and the contributions of the gaussian curves of fat and fibroglandular tissues are not clearly separated.

Dielectric Property Curves	Voxel Intensity
Minimum	0
Fibroglandular_low	$2\times {\mu }_{fg}-M_{fg}$
Fibroglandular_median	${\mu }_{fg}$
Fibroglandular_high	$M_{fg}={\mu }_{fat}-{\sigma }_{fat}-\delta$
Fat_low	${\mu }_{fat}-{\sigma }_{fat}$
Fat_median	${\mu }_{fat}$
Fat_high	${\mu }_{fat}+{\sigma }_{fat}$
Maximum	Maximum intensity of the image
