中文摘要：

该研究针对传统平面电极阵列电阻抗成像系统问题，构建了一个交叉平面电极阵列的电阻抗断层成像系统。此系统由65个电极组成4个水平和8个轴向相交叉的成像空间。仿真及水槽实验采用了Tikhonov正则化算法，重建结果与原物体的比较表明，该成像方式在空间中能够提供更高的分辨率和定位精度。此外，这种方法能有效地减少计算量，在临床检查和监护上显示出很大的应用前景。

英文摘要：

A cross plane electrical impedance tomography system is constructed to solve the problem of the conventional planar electrode array. This system consists of four planar and eight axial cross imaging planes composing from 65 electrodes. The Tikhonov regularization algorithm is adopted for image reconstruction in simulation and flume experiment. Comparison between the reconstruction result and the original object shows that the cross-plane reconstruction method in three-dimensional space provides higher spatial resolution and position accuracy. In addition, it effectively reduces the amount of computation, and reveals great prospect for the application of clinical examination and monitoring.
