Magnetic induction tomography (MIT) is a technique for imaging the electrical conductivity in a cross-section of an object. MIT applies a magnetic field from a current-carrying coil to induce eddy currents in the object which are then sensed by an array of other coils. From these signals, an image of conductivity is reconstructed. This proposal brings together two of the world's leading groups in MIT, from Manchester and South Wales, with a programme designed to address the fundamental theoretical and practical problems of making MIT operate reliably with low-conductivity materials (< 10 S/m). The success of this research could produce a major step forward in the application of MIT, with new opportunities in imaging biological tissues and industrial processes. Three specific application areas will be researched: one biomedical, for imaging acute cerebral stroke, one in glass production, for monitoring process parameters to ensure product quality, and one in the oil industry for imaging the process water in an oil/gas pipeline.

磁感应层析成像（MIT）是一种对物体横截面的电导率进行成像的技术。麻省理工学院从一个载流线圈中施加磁场，在物体中产生涡流，然后由一系列其他线圈感应到。根据这些信号，重建电导率图像。该提案汇集了麻省理工学院来自曼彻斯特和南威尔士的两个世界领先团队，其计划旨在解决使麻省理工学院在低电导率材料（< 10 S/m）下可靠运行的基本理论和实践问题。这项研究的成功可能会使麻省理工学院的应用向前迈出一大步，为生物组织成像和工业过程提供新的机会。将研究三个特定的应用领域：一个是生物医学领域，用于急性脑卒中成像；一个是玻璃生产领域，用于监控工艺参数以确保产品质量；一个是石油工业领域，用于对石油/天然气管道中的工艺水进行成像。
