Magnetic induction tomography (MIT) is a new imaging modality being develop
ed 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 b
e studied, and the magnetic field from these is then detected by sensing co
ils. The technique has been variously named mutual inductance tomography (a
lso MIT) and electromagnetic tomography (EMT). MIT is sensitive to all thre
e passive electromagnetic properties: conductivity, permittivity and permea
bility. 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.
