A
set of high-resolution whole body pregnant woman models at three gestational
stages(3, 6 and 9 months) was adopted to investigate the SAR distribution at
different position and field strength. The highest SAR is occurred in the
mother's peripheral tissues in all pregnancy phase. And the maximum local SAR
of the fetus is over IEC limitation in some cases. The results show that the
local maximum SAR1g and SAR10g can be better indications as limitation factor
other than the whole body average SAR
