摘要

"软场效应"的存在导致电学层析（ET）成像技术重建图像分辨率低

为了度量"软场效应"并降低其影响

提出了一个基于灵敏度系数的"软场效应"度量指标

据此实施ET测量数据的重构。实验结果表明:软场效应指标能够有效地反映"软场效应"对ET成像空间分辨率的影响

重构的数据能够提高已有ET算法的空间分辨率。

Abstract

Reconstructed image by electrical tomography（ ET） has low distinguishability due to its"soft field effect". In order to measure the"soft field effect"and reduce its impacts

a"soft field effect"metrics based on sensitivity coefficient is proposed and use it to implement reconstruction of ET measurement data. Experimental results show that the proposed soft-field indicators can effectively reflect the effects of"soft field effect"on ET imaging spatial resolution

and the reconstructed data can improve the imaging resolution for the existing ET imaging algorithm.
