Abstract ：The principle of magnetic resonance electrical properties tomography (MR EPT) relies on the
fact that the distribution of the transmitted radiofrequency (RF) field characterizes the distribution of
the electrical properties of tissues. The tomography of electrical properties of tissues can be obtained by
utilizing some reconstruction algorithms after the measurement of the transmitted RF field. MR EPT is a
frontier scientific research in the MR field. The aim of this paper is to introduce the principle of MR EPT
and exemplify the principle with the tomographic results of head tissues obtained by the technique of MR
EPT.
