A new reconstruction method, which is called sampled pattern mating method (SPM), has been applied to an ill-posed inverse problem of a capacitance-computed tomography for solid air two-phase flow. As a result, the accuracy of the reconstructed image is improved as compared with a conventional Newton-Rampson iterative method. Moreover, the particles volume ratio in solid air two-phase flow calculated by SPM method is more accurate than the conventional method.
