Abstract. The article is devoted to researching physical factors that influence a patient during magnetic resonance tomography (MRT). Strong static and alternating (gradient) magnetic fields, radio-frequency radiation influence on biological objects is analyzed. The percentage of patients having contra-indications for MRT implementation and side effects occurrence frequency during different types of researches are determined.
Key words and phrases: томография, безопасность, магнитное поле, градиент, радиочастотное воздействие, нагрев тканей, импланты, tomography, safety, magnetic field, gradient, radio-frequency influence, tissues heating, implants
