Electromagnetic tomography or EMT is a
widely-used and very powerful medical imaging technique which detects
and visualises the magnetic/inductive properties of different materials,
namely the various tissues of the human body. More recently, attention
has turned to other potential applications in the industrial and
The objective of this project was to develop
a new process imaging system, based on EMT, suitable for industrial
applications. Research focused on understanding what the technology
could do and what its limitations were - in particular, how fast
the system could capture data so that "moving images"
could be built up.
Several EMT systems were designed and
built. Initial assessments were made of their suitability for use
in the monitoring of hot steel in a strip mill, in non-destructive
parts testing; in the assessment of particle flow in water suspensions
and in detecting salt water fractions in oil and gas pipelines.
Project partners represent the first team
to investigate the suitability of EMT for industrial use and their
findings go well beyond the state of the art. Industrial partners
have been attracted and follow-on projects are being conducted for
two applications in the UK.
