Electrical impedance tomography (EIT) is a noninvasive type of medical imaging in which the electrical conductivity, permittivity, and impedance of a part of the body is inferred from surface electrode measurements and used to form a tomographic image of that part. Electrical conductivity varies considerably among various types of biological ...
If the electrodes are suspended in the boreholes, deeper sections can be investigated. It is closely related to the medical imaging technique electrical impedance tomography (EIT), and mathematically is the same inverse problem. In contrast to medical EIT, however, ERT is essentially a direct current method.
Electrical impedance tomography (EIT) is a non-invasive imaging modality in which a cross sectional image of the conductivity distribution inside an object can be obtained by injecting a set of current patterns and measuring boundary voltages across the electrodes attached to the surface of the object.
EIDORS is an open-source software tool box written mainly in MATLAB/GNU Octave designed primarily for image reconstruction from electrical impedance tomography (EIT) data, in a biomedical, industrial or geophysical setting. The name was originally an acronym for Electrical Impedance Tomography and Diffuse Optical Reconstruction Software.
Electrical impedance tomography (EIT) maps out the electrical conductivity of the ground using a two-dimensional grid of electrodes. Pairs of electrodes receive a small current and the resulting voltages measured on the remaining electrodes.
Many different imaging methods are used in process tomography, e.g. ultrasonic imaging, positron emission tomography (PET), electrical resistance tomography (ERT) and electrical impedance tomography (EIT), electrical capacitance tomography (ECT), magnetic induction tomography (MIT). In all cases external sensors are used to detect signals from ...

Industrial Tomography Systems' scanning technology works on a similar principle to CAT scanners that are used in hospitals to see inside the human body: [12] by passing an electric current very rapidly between pairs of electrodes that are in contact with the process media, real-time images of the industrial process can be extrapolated from measuring the resulting difference in voltages.
