SAR distributions in the abdomen of a pregnant woman generated in a bird cage coil for the MRI system

MRI (magnetic resonance imaging) is an effective method for diagnosis of diseases. During the imaging, RF coil, which is one of the elements of the MRI system, radiates EM (electromagnetic) pulses to the human body and in response receives the NMR (nuclear magnetic resonance) signals emitted from the body. Therefore, it is necessary to estimate the SAR (specific absorption rate) in the human body due to the radiated EM energy from the RF coils. In this study, the SAR in the abdomen of a pregnant woman, especially around the fetus is analyzed by numerical calculations.
