Abstract

The present invention relates to a magnetic induction tomography system and method for studying the electromagnetic properties of an object. In order to provide a high resolution MIT technique without the need of increasing the number of coils, a magnetic induction tomography system (1) for studying the electromagnetic properties of an object (2) is suggested, the system comprising one or more generator coils (4) adapted for generating a primary magnetic field, said primary magnetic field inducing an eddy current in the object (2), one or more sensor coils (5) adapted for sensing a secondary magnetic field, said secondary magnetic field being generated as a result of said eddy current, and means (6, 7, 8, 9) for providing a relative movement between one or more generator coils (4) and / or one or more sensor coils (5) on the one hand and the object (2) to be studied on the other hand.

Description

technical field [0001] The present invention relates to a magnetic induction tomography system and method for studying the electromagnetic properties of an object. Background technique [0002] Magnetic induction tomography (MIT) is a non-invasive imaging technique with industrial and medical imaging applications. In contrast to other electrical imaging techniques, MIT does not require the sensor to be in direct contact with the imaged subject. [0003] MIT applies a magnetic field from one or more generator coils (also known as excitation coils), which induce eddy currents in the material to be studied. In other words, the scanning region is excited with a time-varying magnetic field. The presence of electrically conductive and / or magnetically permeable materials distorts the excitation field within them. Perturbations of the primary magnetic field, ie secondary magnetic fields caused by eddy currents, are detected by a plurality of sensor coils (also called measuring c...
