Abstract :
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.
