Electrical impedance tomography (EIT) is an emerging technology for real-time monitoring based on the impedance differences of different tissues and organs in the human body. It has been initially applied in clinical research as well as disease diagnosis and treatment. Lung perfusion refers to the blood flow perfusion function of lung tissue, and the occurrence and development of many diseases are closely related to lung perfusion. Therefore, real-time monitoring of lung perfusion is particularly important. The application and development of EIT further promote the monitoring of lung perfusion, and related research has made great progress. This article reviews the principles of EIT imaging, lung perfusion imaging methods, and their clinical applications in recent years, with the aim of providing assistance to clinical and scientific researchers.
电阻抗断层成像技术（EIT）是根据人体不同组织器官阻抗差异来进行实时监测的一种新兴技术，目前已被初步运用于临床研究和疾病诊疗。肺灌注是指肺组织的血流灌注功能，许多疾病的发生发展都和肺灌注情况密切相关，所以实时监测肺灌注显得尤为重要，而EIT的应用和发展进一步促进了肺灌注的监测，相关研究已取得极大进展。针对近几年相关研究，本文从EIT成像原理、肺灌注成像方法及其在临床中的应用等几个方面进行综述，以期对临床及科研工作者有所帮助。.
