本文介绍了紧凑型高帧率无源电阻抗断层扫描系统的开发。可以调整注入电流的幅度和频率以适应任何 EIT 应用。测量结果表明，该系统具有89 fps的高帧率，功耗为1.7 W。它具有自动增益控制，可降低噪声并提高测量的EIT图像的质量。与其他 EIT 系统进行比较，以显示所开发系统的潜力。临床相关性——开发的 EIT 系统可应用于新生儿和 SARS-Co V-2 患者的临床评估。在这些应用中，迫切需要一种低成本的床边无创成像系统来连续监测局部肺通气的动态变化
This paper describes the development of a compact high frame rate passive electrical impedance tomography system. The injected current amplitude and frequency can be adjusted to fit any EIT application. Measured results show that the system is capable of high frame rate of 89 fps and has power consumption of 1.7 W. It has automatic gain control that reduces noise and improves the quality of the measured EIT image. A comparison is made with other EIT systems to show the potential of the developed system. Clinical Relevance— The developed EIT system has application in the clinical assessment of neonatal and SARS-Co V-2 patients. In these applications there is an urgent need for a low cost bedside non-invasive imaging system to continuously monitor dynamic changes in regional lung ventilation
