PURPOSE To examine the thermal effects of the physiological response to heating during exposure to radiofrequency (RF) electromagnetic fields in magnetic resonance imaging (MRI) with a head-specific volume coil. MATERIALS AND METHODS Numerical methods were used to calculate the temperature elevation in MRI of the human head within volume coils from 64-400 MHz at different power levels both with and without consideration of temperature-induced changes in rates of metabolism, perspiration… CONTINUE READING
