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.

mapping.
