Since the diversification of the electromagnetic (EM) environment is spreading, it is essential to estimate the EM energy absorption rate [specific absorption rate (SAR)] of a pregnant woman's body and her fetus under various exposure situations. For example, if pregnant women work in jobs where they might wear business portable radios around their abdomens, they should also be concerned about this...
This paper presented evaluation of electromagnetic (EM) energy absorption rate in terms of a specific absorption rate (SAR) in a fetus that was exposed to the EM wave from a portable radio terminal when used in the vicinity of the maternal abdomen. As for the numerical calculation, the electric fields around the antenna were analyzed by the finite-difference time-domain method. We considered analyzing...
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...
The numerical dosimetry of pregnant women is one of the most important issues in electromagnetic-field safety. We have recently developed a whole-body numerical female model of an adult Japanese (non-pregnant) average figure. Therefore, a new fetus model including inherent tissues of pregnant women was constructed based on abdominal MRI data of a 7-month pregnant woman. A whole-body pregnant woman...
