Pulmonary Electrical Impedance Tomography System

WANG Hua-xiang, WANG Chun-yan (School of Electrical Engineering & Automation, Tianjin University, Tianjin 300072 )  
It is very important for pulmonary disease treatment to monitor the pulmonary function continuously. In this paper, the hardware of electrical impedance tomography (EIT) system is designed, and simulative model of human thorax is established for image reconstruction based on Landweber pre-iteration method. Compared with linear back projection, the method above results in the better image reconstruction with little trailing and increased speed of real-time reconstruction.
