呼吸将大量电绝缘空气移入和移出肺部，产生电导率变化，这可以通过电阻抗断层扫描(EIT)看到。因此，自早期EIT研究以来，很明显，呼吸成像可能成为EIT的关键临床应用。在本文中，我们通过对作者在2009-2011年年度生物医学EIT会议的“特殊肺部会议”上的发言进行综述，回顾了肺EIT的现状和未来前景。我们认为，肺EIT研究已经达到了一个重要的转变。现在很清楚，从EIT肺部图像中可以获得有效和可重现的生理信息。我们现在必须问一个问题：如何利用这些数据来帮助改善患者的预后？为了回答这个问题，我们对EIT可能发挥重要作用的临床情景进行了分类，并确定了将EIT转变为临床上有用的肺部监测工具所需的临床和实验研究计划和工程开发。
Breathing moves volumes of electrically insulating air into and out of the lungs, producing conductivity changes which can be seen by electrical impedance tomography (EIT). It has thus been apparent, since the early days of EIT research, that imaging of ventilation could become a key clinical application of EIT. In this paper, we review the current state and future prospects for lung EIT, by a synthesis of the presentations of the authors at the 'special lung sessions' of the annual biomedical EIT conferences in 2009-2011. We argue that lung EIT research has arrived at an important transition. It is now clear that valid and reproducible physiological information is available from EIT lung images. We must now ask the question: How can these data be used to help improve patient outcomes? To answer this question, we develop a classification of possible clinical scenarios in which EIT could play an important role, and we identify clinical and experimental research programmes and engineering developments required to turn EIT into a clinically useful tool for lung monitoring.
