The workshop will be organized in partnership with the center of Modelamiento Matemático (CMM) of the University of Chile in Santiago and will be held Jan. 3-5, 2013 at CMM in Santiago, Chile. The organizers are Matias Courdurier from the Pontificia Universidad Católica de Chile, Jaime Ortega and Axel Osses from CMM and Gunther Uhlmann from the University of Washington. The focus of the conference will be on "coupled-physics" or "hybrid" imaging modalities that have received a lot of attention in recent years due to the great promises they hold for medical imaging and other fields. By combining two or three different types of waves (or physical fields) these methods overcome limitations of classical tomography techniques and deliver otherwise unavailable, potentially life-saving diagnostic information. Among these methods are the Thermoacoustic Tomography (TAT), Photo-Acoustic Tomography (PAT), Ultrasound Modulated Optical and Impedance Tomographies (UMOT, UMEIT), Magneto-Acousto-Electric Tomography (MAET) and several other modalities combining magnetic fields with ultrasound scanning of the tissue. Closely related to these methods are so-called combined physics modalities such as Current Density Imaging and Elastography. Besides medical imaging there has been also recent interest on coupled-physics inverse methods in oil exploration in particular on the Seismo-electric effect.One of the goals of this workshop is to give the participants, in particular junior mathematicians, the opportunity of learning the state of the art in research on coupled-physics inverse problems and discuss future directions and problems. Another goal is to foster the interaction between researchers in inverse problems in Chile, the US and other countries of Latin America, and to also have increased interaction between junior and senior researchers in these fields.

该研讨会将与圣地亚哥智利大学 Modelamiento Matemático (CMM) 中心合作举办，将于 2013 年 1 月 3 日至 5 日在智利圣地亚哥 CMM 举办，组织者是来自 Pontificia Universidad 的 Matias Courdurier。 Católica de Chile、CMM 的 Jaime Ortega 和 Axel Osses 以及华盛顿大学的 Gunther Uhlmann 是会议的焦点。近年来，由于“耦合物理”或“混合”成像模式在医学成像和其他领域的巨大前景，它们通过结合两种或三种不同类型的波（或物理场）而受到广泛关注。 ）这些方法克服了传统断层扫描技术的局限性，并提供了原本无法获得的、可能挽救生命的诊断信息，其中包括热声断层扫描（TAT）、光声断层扫描（PAT）、超声调制光学和成像技术。阻抗断层扫描（UMOT、UMEIT）、磁声电断层扫描（MAET）以及将磁场与组织超声扫描相结合的其他几种模式与这些方法密切相关的是所谓的组合物理模式，例如电流密度成像和弹性成像。除了医学成像之外，最近人们对石油勘探中的耦合物理反演方法也产生了兴趣，特别是地震电效应。本次研讨会的目标之一是提供参与者，特别是初级数学家，有机会了解耦合物理反演问题的研究进展并讨论未来的方向和问题。另一个目标是促进智利、美国和智利的反演问题研究人员之间的互动。拉丁美洲其他国家，并增加这些领域的初级和高级研究人员之间的互动。
