Detailed discussions about the numerical performance of other reconstruction algorithms can be found in [17,28].The above-mentioned algorithms have played an important role in promoting the development of ECT technology and found numerous successful applications. It is worth mentioning that static reconstruction algorithms are often used to image a dynamic object [4,8]. However, these approaches exploit only the spatial relationship of the objects of interest, without using any temporal dynamics of the underlying process, which are not optimal for reconstructing a dynamic object unless the inversion solution is temporally uncorrelated.
ECT measurement tasks often involve time-varying objects, and will be more applicable to image a dynamic object using a dynamic reconstruction algorithm that considers the temporal correlations of a dynamic object.
In the field of ECT image reconstruction, dynamic reconstruction algorithms do not attract enough attention at present. Fortunately, several algorithms, such as the particle filter (PF) technique , the Kalman filter (KF) method  and the four-dimensional imaging algorithm , had been proposed for tackling the dynamic reconstruction tasks. Overall, the investigations of the dynamic reconstruction algorithms in the field of ECT are far from perfect, and finding an efficient dynamic reconstruction algorithm remains a critical issue.
Based on the RPCA method, a dynamic reconstruction model that utilizes the multiple measurement vectors is presented in this paper, where the evolution process of a dynamic object is regarded as a sequence of 2-D images with different temporal sparse AV-951 deviations from a common background.
An objective functional that simultaneously considers the temporal constraint and the spatial constraint is proposed, in which the images are reconstructed in a batching pattern. An iteration scheme that integrates the merits of the ADIO method and the FBS technique is developed for solving the established objective functional. Numerical simulations are Cilengitide implemented to validate the feasibility of the proposed algorithm.The rest of this paper is organized as follows: based on the RPCA method, a reconstruction model that utilizes the multiple measurement vectors is proposed in Section 2.
The original image reconstruction model is formulated into an optimization problem, and a new objective functional is established in Section 3. In Section 4, an iteration scheme that integrates the advantages of the ADIO method and the FBS algorithm is developed for solving the proposed objective functional.
