Combining electrical capacitance and impedance tomography in monitoring processes

The presented research describes an experiment aimed at answering the question of whether the combination of two types of tomographic measurements, namely electrical impedance tomography (EIT) and electrical capacitance tomography (ECT), will improve the quality of the reconstruction in comparison to the tomographic images obtained with both methods considered separately. For this purpose, appropriate tests were carried out, which showed that, in fact, magnification of the measurement vector by combining EIT and ECT measurements increases the quality of the reconstruction.
