本程序结合了2009年6月由曼彻斯特大学主办的电磁逆问题研讨会与会者的部分贡献。该研讨会由本次会议的两位客座编辑组织，并与第10届电阻抗断层成像国际会议平行举行，该会议由Bill Lionheart，Richard Bayford和Eung Je Woo指导。这两项活动都有全体会议和若干选定的会议，将这两项活动合并的一个原因是，目的是将通常可能不参加同一会议的各相关学科的科学家聚集在一起，并加强这些不同群体之间的讨论。因此，例如，讲习班的一天专门讨论地球物理逆问题（包括石油工程中的逆问题）这一更广泛的领域，也鼓励EIT界和医学成像界的与会者参加，并取得了巨大成功。其他会议集中在微波医学成像，逆散射，或涡流成像，积极的反馈也从医学导向的科学家。此外，还举办了多场演讲，涉及光学层析成像、光声层析成像、时间反转或电传感鱼等不同主题。作为研讨会的结果，演讲者被邀请为本次会议贡献扩展论文。所有提交的材料都经过了彻底的审查，并在作者经过深思熟虑的修改后，在本程序中合并。由此产生的六份文件介绍了来自5个不同国家的22位作者的工作，对研讨会上提出的几个主题提供了非常有趣的概述。这些可以分为两个重要类别，即（i）建模和（ii）数据反演。本选集的前三篇论文，如下所述，更多地关注建模方面，作为任何成功反演的重要组成部分，而其他三篇论文讨论了用于特定应用的新型反演技术。在第一篇论文中，标题为A Novel Simplified Mathematical Model for Reynas used in Medical Imaging Applications，作者M J Fernando，M Elsdon，K Busawon和D Smith讨论了一种新的技术，用于模拟跨微带天线的电流，在特定的医学成像应用中，可以非常有效地计算天线的辐射场。这种新的技术，然后测试两个例子，四分之一波长和四分之三波长的天线。下一个贡献，与标题的调查到使用的混合物模型模拟土壤的电性能与不同的有效饱和度水平的地下成像使用ECT由R R海耶斯，P A Newill，F J W Podd，T A约克，B D Grieve和O多恩，考虑开发一种新的可视化工具，用于监测某些种子育种植物周围的土壤水分含量。电容层析成像技术用于验证每种植物如何有效地利用周围土壤中的水分和养分。本研究的目的是帮助开发和识别新的耐旱粮食作物。在第三贡献组合的最大极小和克里格预测方法的涡流检测数据库生成S Bilicz，M兰伯特，E巴斯克斯和S Gyimóthy，提出了一种新的数据库生成技术，用于解决逆涡流检测问题。为了避免昂贵的重复正向模拟过程中创建这个.
This proceeding combines selected contributions from participants of the Workshop on Electromagnetic Inverse Problems which was hosted by the University of Manchester in June 2009. The workshop was organized by the two guest editors of this conference proceeding and ran in parallel to the 10th International Conference on Electrical Impedance Tomography, which was guided by Bill Lionheart, Richard Bayford, and Eung Je Woo. Both events shared plenary talks and several selected sessions.One reason for combining these two events was the goal of bringing together scientists from various related disciplines who normally might not attend the same conferences, and to enhance discussions between these different groups. So, for example, one day of the workshop was dedicated to the broader area of geophysical inverse problems (including inverse problems in petroleum engineering), where participants from the EIT community and from the medical imaging community were also encouraged to participate, with great success. Other sessions concentrated on microwave medical imaging, on inverse scattering, or on eddy current imaging, with active feedback also from geophysically oriented scientists. Furthermore, several talks addressed such diverse topics as optical tomography, photoacoustic tomography, time reversal, or electrosensing fish.As a result of the workshop, speakers were invited to contribute extended papers to this conference proceeding. All submissions were thoroughly reviewed and, after a thoughtful revision by the authors, combined in this proceeding. The resulting set of six papers presenting the work of in total 22 authors from 5 different countries provides a very interesting overview of several of the themes which were represented at the workshop. These can be divided into two important categories, namely (i) modelling and (ii) data inversion. The first three papers of this selection, as outlined below, focus more on modelling aspects, being an essential component of any successful inversion, whereas the other three papers discuss novel inversion techniques for specific applications.In the first contribution, with the titleA Novel Simplified Mathematical Model for Antennas used in Medical Imaging Applications, the authors M J Fernando, M Elsdon, K Busawon and D Smith discuss a new technique for modelling the current across a monopole antenna from which the radiation fields of the antenna can be calculated very efficiently in specific medical imaging applications. This new technique is then tested on two examples, a quarter wavelength and a three quarter wavelength monopole antenna.The next contribution, with the titleAn investigation into the use of a mixture model for simulating the electrical properties of soil with varying effective saturation levels for sub-soil imaging using ECTby R R Hayes, P A Newill, F J W Podd, T A York, B D Grieve and O Dorn, considers the development of a new visualization tool for monitoring soil moisture content surrounding certain seed breeder plants. An electrical capacitance tomography technique is employed for verifying how efficiently each plant utilises the water and nutrients available in the surrounding soil. The goal of this study is to help in developing and identifying new drought tolerant food crops.In the third contributionCombination of Maximin and Kriging Prediction Methods for Eddy-Current Testing Database Generationby S Bilicz, M Lambert, E Vazquez and S Gyimóthy, a novel database generation technique is proposed for its use in solving inverse eddy-current testing problems. For avoiding expensive repeated forward simulations during the creation of this …
