At last years ISMRM meeting, we introduced Local Maxwell Tomography (LMT) a method for noninvasive mapping of electrical conductivity and permittivity using incomplete MR-based measurements of RF field curvature. Here, we apply a theoretical framework analogous to that of LMT to solve Pennes bio-heat equation, instead of Maxwells equations, and thereby to reconstruct tissue thermal property maps from MR thermometric measurements. We outline the theory and demonstrate reconstruction of thermal properties such as heat capacity, thermal conductivity, and metabolic energy rate.
