MAGNETIC RESONANCE (MR) TOMOGRAPHY OF ELECTRICAL PROPERTIES Russian patent published in 2017 - IPC A61B5/55 A61B5/53 G01R33/44 G01R33/48 

FIELD: medicine.

SUBSTANCE: inventions refer to medical equipment, namely to magnetic resonance imaging means. The method of magnetic resonance imaging for an object comprises stages when the object is exposed to action of two or more of the imaging sequences to obtain MR signals, each imaging sequence comprises a radio frequency (RF) pulse and a switchable magnetic field gradient, two or more images of MR phase of MR signals obtained by the two imaging sequences are reconstructed, in which the switched magnetic field gradients of one imaging sequence for spatial encoding in MR imaging have opposite polarity relative to switched magnetic field gradients of the second imaging sequence, spatial distribution of the object electrical properties is derived. The MR device is designed for method implementation, at that, the MR device includes a main electromagnet coil, a set of gradient coils for switched magnetic field gradients generation, a RF coil, a control unit and a reconstruction unit. The data medium for the magnetic resonance imaging systems comprises a computer program for execution on the MR device.

EFFECT: group of inventions enables extending of the technical means of tomography.
