二、工作原理（Working Principle）
中文
采用电阻抗断层成像（EIT） 核心技术：在患者胸部环绕布置 16 电极阵列，通过相邻电极分时施加生物安全微弱交流电流，同步采集其余电极间的边界电压信号；基于欧姆定律与肺部通气 / 灌注导致的阻抗变化规律，经图像重建算法解算胸腔横断面的电阻抗分布，实时生成肺通气动态图像、阻抗波形及功能参数，直观反映肺内气体分布与动态变化。
English
Adopts core technology of Electrical Impedance Tomography (EIT): A 16‑electrode array is placed around the patient’s chest. Weak, bio‑safe alternating current is applied sequentially through adjacent electrodes, and boundary voltage signals between remaining electrodes are collected simultaneously. Based on Ohm’s law and impedance changes caused by pulmonary ventilation/perfusion, image reconstruction algorithms calculate the electrical impedance distribution of the thoracic cross‑section, generating real‑time dynamic lung ventilation images, impedance waveｆorms, and functional parameters to visually reflect intrapulmonary gas distribution and dynamic changes.
