Abstract

Magnetic induction tomography (MIT) is a lowresolution imaging modality used for reconstructing the changes of the passive electrical properties in a target object. For EIT the theoretical limits of image quality have been studied carefully while no such study exists for MIT. Thus a simplified analysis on resolution and object shifting was carried out for our linear reconstruction scheme in order to have a theoretical basis for interpreting our results. In analogy to EIT the PSF depends strongly on the location, showing the broadest distribution in the centre of the cylinder. Increasing the amount of regularization according to increasing measurement noise the PSF broadens and its centre is shifted towards the borders of the cylinder.
