中文摘要：
医学上，电的阻抗断层摄影术(EIT ) 与计算机化的断层摄影术(CT ) 和磁性的回声成像(MRI ) 相比是一种相对便宜、安全、非侵略、便携式的技术。在这篇论文， EIT_TJU_II 系统被开发包括数据收集系统和图象重建算法。包括空间分辨率和敏感，系统表演的严峻的途径通过盐水坦克实验被描述。胸的图象物理模型证实系统能重建内部抵抗力分发。最后，肺通风在 vivo 的功能的监视被 EIT 认识到，并且设想的图象显示 EIT_TJU_II 系统的配置和性能是可行的， EIT 是在临床的监视的一种有希望的技术申请。
英文摘要：
Medically, electrical impedance tomography （EIT） is a relatively inexpensive, safe, non-invasive and portable technique compared with computerized tomography （CT） and magnetic resonance imaging （MRI）. In this paper, EIT_TJU_ II system is developed including both the data collection system and image reconstruction algo- rithm. The testing approach of the system performance, including spatial resolution and sensitivity, is described through brine tank experiments. The images of the thorax physical model verify that the system can reconstruct the interior resistivity distribution. Finally, the lung ventilation functional monitoring in vivo is realized by EIT, and the visualized images indicate that the configuration and performance of EIT_TJU_ II system are feasible and EIT is a promising technique in clinical monitoring application.
