Abstract (in Japanese) (See Japanese page) 
(in English) Imaging the conductivity and permittivity of the human body using magnetic fields measured by MRI is expected as a new modality for cancer diagnosis. We have proposed a method to reconstruct the electrical properties by calculating the electric field from the measured magnetic field, but it was necessary to assume that all the values of the electric properties on the ROI boundary were known. In this study, we propose a method to estimate the electric field and electrical properties using only a few values of the electric properties on the boundary by using the boundary element method, and the validity of the method is verified by simulation.
