| Research Abstract |
Magnetic resonance imaging (MRI) is an effective method for diagnosis of diseases. The MRIradiates electromagnetic (EM) wave to the body under the high field static magnetic field.Therefore, it is necessary to estimate the EM energy absorption in the human body due to theradiated EM wave. Especially, in this study, EM energy absorption in the abdomen of pregnantwoman and her fetus are investigated by numerical calculations. As a result of the calculations,the EM energy absorption of the fetus is low and does not expected to be teratogenic.
