摘要

本文介绍了用于电阻抗断层成像(EIT)图像在线定性重建和分析的动态链接库(DLL)和信号调理系统的实现。三种不同的有限元圆网格被开发用于DLL: 104,464和1016三角形单元。该库允许用户在三种不同的重建后数据可视化选项之间进行选择:原始数据，双线性插值和径向基函数(RBF)插值。因此，DLL可以导入到虚拟仪器软件中，例如National Instruments LabWindows©和Agilent Technologies HPVEE©，以简化EIT测量的虚拟仪器的实施。给出了一个实例研究:在实验室测试试验中进行幻影内目标跟踪。结果表明，EIT DLL可以作为虚拟仪器程序的一部分使用，减少了多种应用中在线实时分析的开发时间。

Dynamic Link Library and Signal Conditioning System for Electrical Impedance Tomography Virtual Instrumentation

This paper presents the implementation of a Dynamic Link Library (DLL) and Signal Conditioning System for on-line qualitative reconstruction and analysis of Electrical Impedance Tomography (EIT) images. Three different finite element circular meshes were developed for use with the DLL: 104, 464 and 1016 triangular elements. The library allows the user to choose between three different post-reconstruction options for data visualization: raw data, bilinear interpolation and radial basis function (RBF) interpolation. The DLL can thus be imported into a Virtual Instrumentation software, such as National Instruments LabWindows© and Agilent Technologies HPVEE© to ease the implementation of virtual instrumentation for EIT measurements. A case study is presented: in-phantom object tracking in laboratory test trials. The results suggest that the EIT DLL can be used as part of a virtual instrumentation program, reducing development time for on-line real-time analysis in multiple applications.
