Multiple Measurement Vector-Based Complex-Valued Multifrequency ECT

Complex-valued, multifrequency electrical capacitance tomography (CVMF-ECT) is a recently developed tomographic concept which capable of simultaneously reconstructing spectral permittivity and conductivity properties target objects within the region interest. To date, this has been limited to simulation another key issue restricting its wide adoption lies in poor image quality. This letter reports CVMF-ECT system verify practical feasibility further proposes novel reconstruction framework effectively efficiently reconstruct images using complex-valued data. The utilizes inherent spatial correlations as priori information encodes it by multiple measurement vector (MMV) model. Alternating direction method multipliers was introduced solve MMV problem. Real-world experiments validate CVMF-ECT, MMV-based demonstrates superior performance compared with conventional ECT approaches.
