电阻抗断层成像的 MPSO-MNR 算法研究
MPSO-MNR algorithm study of 2-D electrical impedance tomography
摘要
Abstract
This paper which is based on the advantages and limits of the Modified Particle Swarm Optimization(MPSO)algo-rithm and Modified Newton-Raphson(MNR)algorithm proposes the MPSO-MNR algorithm, and presents the numerical simula-tion of 2-D Electrical Impedance Tomography(EIT). In this paper, the MPSO-MNR algorithm is used to study the imaging of the EIT. The circle-domain solved is discretized into irregular polygons by the Finite Element Method(FEM). Trigonometric current pattern and the MPSO-MNR are adopted to reconstruct the impedance distribution, and the reconstruction results are evaluated by the fitness value function and the total error. The numerical simulation results show that the MPSO-MNR algorithm can locate the targets accurately and reflect the impedance distribution within certain iterations.关键词
