A reconstruction method for electrical capacitance tomography based on image fusion techniques

In this work, a method based on image fusion for the formation of Electrical Capacitance Tomography (ECT) images is presented. This method is based on the modification of the classical algebraic superposition of sensitivity maps, weighted with the inter-electrode capacitance measurements, which is the basis of most of the existing image reconstruction algorithms. This fusion-based approach replaces this superposition with the scalar multiplication of partial images generated considering only the data corresponding to fixed source electrodes. Results obtained with this new method show that the quality of the images can be improved without any image post-processing, which is very interesting especially for real-time applications.
