摘要：
The low spatial resolution and poor stability of electrical tomography are caused by the soft field effect and undetermined problem of the measured object field. In order to overcome the effect of soft field, the key influence of sum of the sensitivity coefficients on the spatial resolution is analyzed in electrical tomography. A novel electrical tomography algorithm based on sensitivity coefficient is proposed. The experimental results show that the method can effectively overcome the inherent problem of electrical tomography. It reduces the error of reconstructed image by 5%-8%, and improves the resolution of small target space for discrete distributions. © 2017, Editorial Board of Journal of Tianjin University(Science and Technology).
