The principal features of an electrical impedance tomography system using induced currents are described. Images of the distribution of conductivity in a two-dimensional phantom are obtained using an algorithm based on a sensitivity matrix. Results are also presented which demonstrate the separation of conductivity and permittivity images from measurements of the complex peripheral voltage, the formation of unreferenced permittivity images, and the use of capacitively coupled electrodes in a measuring system without direct electrical contact.
描述了一种使用感应电流的电阻抗断层成像系统的主要特征。使用基于灵敏度矩阵的算法获得二维模型中电导率分布的图像。还给出了一些结果，这些结果展示了从复周边电压测量中分离电导率和介电常数图像、形成无参考介电常数图像以及在无直接电接触的测量系统中使用电容耦合电极的情况。
