电容层析成像技术中影响图像重建质量的因素分析

电容层析成像技术（ECT）作为一种多相流参数检测技术，具有快速、非侵入、结构简单、无辐射、成本低等特点，而图像重建质量和速度是阻碍电容层析成像技术工业应用的关键性问题，本文讨论了影响图像重建的因素，在采用线性反投影算法、正则化求逆算法以及迭代法的基础上，研究了单元划分数目、有限元形状、极板数以及介电常数四种因素对成像质量的影响．研究结果对获得最佳成像效果具有一定的指导意义．

An Analysis of Factors Affecting ECT Image Reconstruction

As a measure technology for testing parameters of multi-phase flow,Electrical Capacitance Tomography(ECT) has the characteristics of non-intrusion,non-radiation,low cost,fast response,easy to implement.The quality and rate of image reconstruction are critical for application of ECT in practical industries.In this paper,ECT image reconstruction algorithms,LBP,Landweber iteration,and MLRR are used to analyze the four factors that affect the reconstructed image quality including the number,the shape of pixel,t...
