Practical application of electrical impedance tomography and electrical resistive tomography

摘要

Usage of electrical impedance tomography and electrical resistance tomography will be in the article. The electrical impedance tomography is a widely investigated problem with many applications in physical and biological sciences. Medical imaging can be used primarily for the detection of pulmonary emboli, non-invasive monitoring of heart function and blood flow, and for breast cancer detection. Electrical resistive tomography is use in the geophysical imaging is used for searching underground conducting fluid plumes near the surface and obtaining information about rock porosity or fracture formation. Another application of electrical impedance tomography is for example in non-destructive testing and identification of material defects like cracks or identification of corrosion in production materials. The principle of electrical impedance tomography and Electrical resistive tomography is based on the back image reconstruction, which is highly ill-posed inverse problem. The aim of both methods is to reconstruct, as accurately and fast as possible, the internal impedance or conductivity distributions in two or three dimensional models.
