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 ...
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.
2D resistivity inversion of ERT data Deployment of a permanent electrical resistivity tomography profile on a longitudinal section of an active landslide.. Electrical resistivity tomography (ERT) or electrical resistivity imaging (ERI) is a geophysical technique for imaging sub-surface structures from electrical resistivity measurements made at the surface, or by electrodes in one or more ...
Process tomography [2] consists of tomographic imaging of systems, such as process pipes in industry. In tomography the 3D distribution of some physical quantity in the object is determined. There is a widespread need to get tomographic information about process.
Tomography is imaging by sections or sectioning that uses any kind of penetrating wave. The method is used in radiology , archaeology , biology , atmospheric science , geophysics , oceanography , plasma physics , materials science , cosmochemistry , astrophysics , quantum information , and other areas of science .
Electrical capacitance tomography (ECT) is a method for determination of the dielectric permittivity distribution in the interior of an object from external capacitance measurements. It is a close relative of electrical impedance tomography [ 2 ] and is proposed as a method for industrial process monitoring.

He first proposed the idea of electrical impedance tomography as a medical imaging technique in a publication in 1978. [ 3 ] In his spare time, Webster worked with undergraduate biomedical engineering design teams at the University of Wisconsin-Madison, including ongoing projects with impedance cardiography and atrial fibrillation.
