MIT applies a magnetic ?eld from an excitation coil to induce eddy currents in the material to be studied, and the magnetic ?eld from these is then detected by sensing coils. The technique has been variously named mutual inductance tomography (also MIT) and electromagnetic tomography (EMT). MIT is sensitive to all three passive electromagnetic properties: conductivity, permittivity and permeability. A number of experimental systems exist but so far no MIT system has reached routine use either industrially or medically. There is a need for the two research communities to work more closely together to further their joint aim in making MIT a successful imaging modality. 摘要 磁感应断层成像技术（MIT）是一种新兴的成像方式，MIT用于工业和医学成像。在被研究的材料中，磁感应成像运用于励磁线圈磁场感应涡流，并且这产生的磁场是通过感应线圈检测。该技术已被不同地命名为互感层析成像（MIT）和电磁层析成像（EMT）。MIT对三个被动电磁特性都敏感：电导率、介电常数和磁导率。大量实验系统存在，但至今没有MIT系统能达到工业或医学的日常使用。有必要让这两个研究团体更紧密地合作，以深入发展使MIT成为一个成功的成像方式的共同目标。 Keywords: magnetic induction tomography, electromagnetic tomography 关键词：磁感应断层成像，电磁层析成像 Introduction In the last 15 years much research effort has been devoted to the development of tomographic techniques for imaging the low-frequency (2 MHz), passive electromagnetic properties of materials non-invasively. Most of this interest has been in the areas of medical imaging, w
