摘要
应用 2D -阻抗法和由人体头部横断面切片获得的头部二维模型 ,计算人体头部在磁共振成像 (magneticresonanceimaging ,MRI)检查中由RF线圈产生的B1场作用下比吸收率 (specificabsorptionrates,SAR)的分布 。
The 2D-impedance method and two dimension human head model acquired by transverse section of human head were used to computer the SAR distribution in human head effected by the B 1 field excited by RF coils during MRI. The SAR distribution in human head during MRI and the problem related were studied.
