Comparing Shape and Image Reconstruction in Electrical Capacitance Tomography

Electrical capacitance tomography (ect) is an imaging technique that maps the electrical permittivity contrast of the object. this paper studies an image and a shape reconstruction method for ect. for image reconstruction, a regularized gauss-newton method has been implemented, based on the inverse finite element technique. for shape reconstruction, a narrowband level set method has been developed. using experimental ect data, a comparative study of these two techniques is the main objective of this paper
