摘要

基于谢菲尔德系统DAS01P-01的测量数据，采用两种算法构建了动态电阻抗层析成像(EIT)图像。一种是从静态图像派生出动态图像。另一种是利用反向投影法重建动态图像。确定并比较了感兴趣区域电阻率的变化。讨论了两者的差异及可能的原因。

Comparison and analysis of electrical impedance tomographic images reconstructed using two algorithms

Dynamic electrical impedance tomographic (EIT) images are constructed based on the measurements from Sheffield system DAS01P-01 using two algorithms. One is to derive dynamic images from static images. Another is to reconstruct dynamic images using the back projection method. Changes of resistivity in region of interests (ROI) are determined and compared. The difference and possible reasons are discussed.
