Abstract :
Calderon´s method was introduced to electrical capacitance tomography with square sensor in this paper. It is a direct algorithm of the image reconstruction, as no matrix inversion or iterative process is needed. It was implemented through numerical integration. Since the Gauss-Legendre quadrature was applied and can be predetermined, the image reconstruction process was fast and resulted in images of good quality. Simulated results validated the feasibility and effectiveness of Calderon´s method in electrical capacitance tomography with square sensor.
