Thesis (S.B.)--Massachusetts Institute of Technology, Dept. of Physics, 2006. === Includes bibliographical references (leaf 43). === The human body is composed primarily of dielectric tissue with spatially varying permittivity and conductivity. Traditional MRI does not measure these properties. Instead, the conductivity of the patient is a nuisance, causing unpredictable detuning of coils and field inhomogeneities. This thesis presents a method for mapping the electrodynamic properties of the patient's body with both MR and non-MR techniques. Such mapping has direct applications for medical imaging and SAR calculation. === by Benjamin M. Schwartz. === S.B.
