摘要
计算了平面矩形螺旋线圈的电感值,结果与近似公式计算得出的电感值吻合。另外,通过理论计算发现,矩形平面螺旋线圈产生的磁场具有聚焦的特性,并计算和讨论了分层生物组织的电导率对电感的影响,认为用矩形平面螺旋线圈来做生物组织非接触的电导率成像的激励线圈是可行的。
The inductance of the rectangular plan spiral coil is calculated. The calculated results are in accordance with the results calculated by approximate formula. It is found that the magnetic fields produced by the rectangular plan spiral coil can focus in a very small area. The changes of inductance by the conductivity of each layer of tissue are analyzed,then. The conclusion is that the rectangular plan spiral coil can be used as the exiting coil for contactless magnetic induction tomography of biological tissue.
