摘要

电阻抗断层成像(EIT)中的图像重建是一个病态最小化问题。在这里，作者研究了食道参考电极改善EIT图像的效用。在计算机模拟中，利用食管电极的重建方案在重建误差和执行速度方面优于完全依赖边界电压的两种配置。

Utility of an esophageal reference electrode for thoracic electrical impedance tomography

Image reconstruction in Electrical Impedance Tomography (EIT) is an ill-conditioned minimization problem. Here, the authors examine the utility of an esophageal reference electrode to improve EIT images. In a computer simulation, a reconstruction scheme utilizing an esophageal electrode outperformed two configurations relying entirely on boundary voltages in terms of both reconstruction error and speed of execution.
