摘要翻译:
电阻抗断层成像(EIT)是一种不使用电离辐射的无创成像技术,在环境科学和卫生领域都有应用。图像重建是通过求解一个反问题和不适定问题来进行的。进化计算和群体智能已经成为解决反问题的一个方法来源。鱼群搜索(FSS)是一种基于鱼群动态特性的搜索和优化方法。本文提出了一种基于FSS和非盲搜索(NBS)的EIT图像重建方法。该方法用由电导率图像组成的数值模型进行了评估,实验对象位于圆形截面的中心、中心与边缘之间以及边缘上,网格由415个有限元组成。作者对每个配置进行了20次模拟。结果表明,FSS算法和FSS-NBS算法的收敛速度都快于遗传算法。

英文摘要:
Electrical Impedance Tomography (EIT) is a noninvasive imaging technique that does not use ionizing radiation, with application both in environmental sciences and in health. Image reconstruction is performed by solving an inverse problem and ill-posed. Evolutionary Computation and Swarm Intelligence have become a source of methods for solving inverse problems. Fish School Search (FSS) is a promising search and optimization method, based on the dynamics of schools of fish. In this article the authors present a method for reconstruction of EIT images based on FSS and Non-Blind Search (NBS). The method was evaluated using numerical phantoms consisting of electrical conductivity images with subjects in the center, between the center and the edge and on the edge of a circular section, with meshes of 415 finite elements. The authors performed 20 simulations for each configuration. Results showed that both FSS and FSS-NBS were able to converge faster than genetic algorithms.
