An Improved Back-projection Algorithm of Dynamic Electrical Impedance Tomography

Xu Guanxin1 He Wei1 H.Singer2 1 (College of Electrical Engineering, Chongqing University, Chongqing 400044,China) 2 (TU Hambug-Harburg, Germany)  
In this paper, an improved back-projection algorithm of dynamic electrical impedance tomography (EIT) was described. The improved back-projection algorithm modified the computing method of back-projection matrix B. Dynamic reconstruction image was obtained by the improved algorithm, and it was compared to the image obtained by the traditional method of equi-potential back-projection. The results showed that the improved algorithm of equi-potential back-projection could locate the object's position in the field with higher precision, and its speed was very fast. It also could improve the resolution of the reconstructed image in some extent.
