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.
