This is because the outer material acts as an electromagnetic screen, which partially excludes the magnetic field from the interior space and hence reduces the sensitivity at the centre. In this paper, we propose a methodology to image the conductivity distribution of an annular object when internal conductive objects are present. Finite element simulations were carried out to investigate how sensor coil outputs change with factors such as the size of internal object with regards to the external one. Linear and non-linear image reconstruction methods are applied to the tomographic data that are collected from a newly developed EMT system and image results are given in the paper.Electronic instrumentsCongressesMeasurementCongressesElectronic instrumentsMeasurement620.0028PQKBPROCEEDING99101426717033212006 IEEE Instrumentation and Measurement Technology Conference2494666UNINA
