Particle distribution in a pipeline has been clearly visualized by a combination of capacitance computed tome graphy and comvolution processing. The particle distribution just after the plugging point gets partial on a cross section. In the pipeline, clay attached inside in order to simulate near plugging. The CT obtains the capacitance between 12 electrodes distributed around the outside of the pipeline. The particle and air distributions can be separated because of individual permittivity by the reconstruction technique. The technique calculates the permittivity distribution on the cross section from the capacitance values by an iterative method of inverse problem.
