In-vivo estimation of electrical properties of biological tissues is relevant in several medical applications, ranging from hyperthermia treatment planning to dosimetry. In this contribution, we propose a novel inverse scattering approach addressing this problem. In particular, the approach is based on inverting phaseless boldsymbol{B} {1} {+} measurements acquired in a magnetic resonance scanner. Moreover, it takes advantage of an innovative use of the segmented anatomy model derived by magnetic resonance images in order to regularize the inverse scattering problem.
