摘　　要：我国的电阻抗断层成像(electrical impedance tomography,EIT)研究已具备相当基础,一些关键技术和针对某些应用目标的研究已达到国际先进水平,从EIT方法学研究向实用化应用研究过渡的时机已经成熟。我国的EIT研究仍然需要向深度和广度发展,但是目前研究重点应该集中在某些确定应用目标的实用化应用研究方面。在原有方法学研究成果的基础上,有针对性地深入研究生物组织和器官的电特性;提取在细胞层次上发生的、与人体生理、病理状态相联系的功能性或前瞻性信息;重点发展用于乳腺肿瘤早期发现,体内渗血的无损检测与监护,区域性肺通气功能以及胃动力检测与评价等EIT应用技术;建立可用于临床检测的实用化EIT系统,进入临床应用研究。Up to now much progress of the research on electrical impedance tomography （EIT） in China has been made. Some key technology and studies on application objects in EIT have reached world levels. It is the time for EIT to develop from the methodology research to the practical application research. Although the EIT research needs to be developed deeply and widely,at present the important task is to focus on EIT practical application research on some specific objects. Based on the achievements in methodology research, the main tasks are to investigate electric property of tissue and organ in human body, as well as pay attention to the extraction of functional and portentous informations which happen at the cell level and are related to physiology and pathology state of human body;to focus on the development of EIT application technology for early detection of breast tumor, internal hemorrhage monitoring in body, regional lung ventilation imaging, the measurement and evaluation of gastric motility function, and so on.Practical EIT clinical measurement system which would be applied in clinical research should be set up.
