Electrical impedance tomography (EIT) is a relatively new imaging method that has evolved over the past 20 years. It has the potential to be of great value in clinical diagnosis; however, EIT is a technically difficult problem to solve in terms of developing hardware for data capture and the algorithms to reconstruct the images. This review looks at the development of EIT and how it has evolved. It focuses on its clinical applications, examining hardware for the collection of data and reconstruction algorithms to generate images. Finally, this review looks at future developments that are evolving from EIT. These new variations use mixed modalities that may produce interesting new clinical imaging tools.
电阻抗断层成像（EIT）是一种相对较新的成像方法，在过去20年中得到了发展。它在临床诊断中具有巨大的潜在价值；然而，就开发用于数据采集的硬件和图像重建算法而言，EIT是一个技术上难以解决的问题。本文综述了EIT的发展历程及其演变方式。它重点关注其临床应用，研究用于数据采集的硬件和生成图像的重建算法。最后，本文综述了从EIT衍生出的未来发展。这些新的变体使用混合模式，可能会产生有趣的新型临床成像工具。
