摘要

模拟了用感应电流电阻抗成像检测癫痫病灶的方法。模拟使用三维有限元模型来确定测量系统所需的灵敏度，以便检测以边长为10mm的立方体表示的癫痫病灶，其电导率变化为10%。结果表明，该系统可以对区域边缘附近的焦点进行成像，但对中心附近的焦点成像效果较差。

Imaging of the head using induced current impedance tomography

The use of induced current electrical impedance imaging to detect epileptic foci has been simulated. The simulation uses a three dimensional finite element model to determine the sensitivity required of the measuring system in order to detect an epileptic focus represented as a cube of side 10 mm with a 10% change of conductivity. It is shown that the system can image foci near the edge of the region, but is less successful near the centre.
