英文摘要：

This paper proposed a post-process method for 2D-EIT-based（Two Dimensional Electrical Impedance Tomography） PE（Position Error） and relative QI（Quantity Index）, which was intended to identify the distribution of multiple electrical conductivity, organ compositions as well as position information. Additionally, an integrated TR（Tikhonov Regularization） based on two present construction algorithms was also introduced and compared. According to the results, this post-process method could improve the placement accuracy and spatial resolution of 2D EIT, which made EIT applicable for clinical examinations and process monitoring.
