Syamsul Ma’arif, BS Thesis, Dept. of Physics, University of Indonesia, 2008
A dynamic volume imaging based on the principle of electrical capacitance tomography (ECT), namely, electrical capacitance volume tomography (ECVT), has been developed in this research. The technique generates, from the measured capacitance, a whole volumetric image of the region enclosed by the geometrically three-dimensional capacitance sensor. This development enables a real-time, 3-D imaging of a moving object or a real-time volume imaging (4-D) to be realized. The development of the ECVT imaging technique primarily encloses the 3-D capacitance sensor design to get the optimum image and image volume reconstruction technique. The image reconstruction technique is modified by introducing into the algorithm a 3-D sensitivity matrix. The Distribution of sensitivity affects the produced image. The research is done with the simulation system and computational electric field in COMSOL Multiphysics software that is based in a finite element method and calculated in MATLAB 2007b and is examined with hardware.
