In this paper we demonstrate that conductivity changes caused by ventilation and perfusion in a human subject can be reconstructed from electrical impedance tomography data collected on a rectangular array of electrodes placed on a subject's chest. Currents are applied on the electrodes and the resulting voltages on the electrodes are measured. A 3D reconstruction algorithm is used to reconstruct the conductivity distribution in the region beneath the array. Time traces of the reconstructed conductivity distribution demonstrate the detected changes in conductivity due to ventilation and perfusion.
在本文中，我们证明了通过放置在人体胸部的矩形电极阵列收集的电阻抗断层扫描数据，可以重建人体受试者因通气和灌注引起的电导率变化。在电极上施加电流，并测量电极上产生的电压。使用三维重建算法来重建阵列下方区域的电导率分布。重建的电导率分布的时间轨迹显示了由于通气和灌注而检测到的电导率变化。
