磁感应层析成像（MIT）是一种新的成像方式正在发展的过程工业和医学成像。麻省理工学院应用一个来自激励线圈的磁场，在被研究的材料中产生涡流，然后由感应线圈检测到这些磁场。该技术被称为互感层析成像（也称为MIT）和电磁层析成像（EMT）。MIT对所有三种无源电磁特性都很敏感：电导率、介电常数和磁导率。有许多实验系统存在，但到目前为止，麻省理工学院的系统还没有达到工业或医学上的常规应用。这两个研究团体有必要更紧密地合作，以进一步实现他们的共同目标，使麻省理工学院成为一个成功的成像模式。
Magnetic induction tomography (MIT) is a new imaging modality being developed for the process industry and for medical imaging. MIT applies a magnetic field from an excitation coil to induce eddy currents in the material to be studied, and the magnetic field 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.
