本文研究了将电极放置在 3D 圆柱形介质上的几种配置，以使用旨在与 2D 相邻驱动协议一起使用的 16 电极 EIT 设备重建 3D 图像。根据以下品质因数对七种不同的电极放置配置进行了比较：分辨率、径向和垂直位置误差、图像幅度、抗噪声能力、抗电极放置误差能力以及图像伪影的定性评估。结果表明，在理想条件下，所考虑的配置没有一个性能明显优于其他配置。然而，当考虑噪声和电极放置误差时，平面电极放置配置（两个垂直对齐的电极环，每个环中依次放置电极）具有整体最佳性能。根据这些结果，我们建议采用平面电极放置配置进行胸部 3D EIT 肺部成像。
This paper investigates several configurations for placing electrodes on a 3D cylindrical medium to reconstruct 3D images using 16 electrode EIT equipment intended for use with a 2D adjacent drive protocol. Seven different electrode placement configurations are compared in terms of the following figures of merit: resolution, radial and vertical position error, image magnitude, immunity to noise, immunity to electrode placement errors, and qualitative evaluation of image artefacts. Results show that for ideal conditions, none of the configurations considered performed significantly better than the others. However, when noise and electrode placement errors were considered the planar electrode placement configuration (two rings of vertically aligned electrodes with electrodes placed sequentially in each ring) had the overall best performance. Based on these results, we recommend planar electrode placement configuration for 3D EIT lung imaging of the thorax.
