<title>Analysis of capacitance sensitivity distributions and image reconstruction in electrical capacitance tomography</title>

This paper describes a tomographic method is based on 8- electrode capacitance sensor. It discusses the application if finite element method in electrical capacitance tomography, and a finite element model of 8-electrode capacitance sensor is established. Capacitance sensitivity distributions can be analyzed with this method. Satisfactory images can be reconstructed by using the capacitance sensitivity distributions as a priori information. It provides powerful support for further application research.
