Paper Abstract

This paper describes a tomographic method is based on 8-electrode capacitance sensor. It discusses the application of 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 and optimal sensor design can also be done with it. A novel image reconstruction algorithm based on genetic algorithm is presented to improve quality of image reconstruction and calculating accuracy of concentration, satisfactory images can be reconstructed by using the capacitance sensitivity distributions of optimally designed system as a priori information. It provides powerful support for further application research.
