Abstract. The capabilities and expediency of using traditional methods of heating thermo diffusion from mini electric heaters for systems of MR thermometry is investigated. Methods of combine use of conductive sources of heat (electric heaters, based on high-resistant wire) with MRI equipment and methods of real time monitoring of thermal effects, caused by heating, are described. Spatio-temporal dynamics of metal artefacts, inducted by material of electric heaters and their magnetic fields is demonstrated on model objects.

Key words: Magnetic-resonance imaging (MRI), MR-thermometry, non-invasive thermometry, MRI temperature mapping.
