چکیده
Diagnostic technologies using X-rays and/or acoustic emissions for concrete infrastructures containing internal pores, defects, and cracks have attracted considerable interest. However, computerized tomography (CT) is challenging due to its radiation shielding characteristics. Electrical impedance (EIT), initially developed medical use, has recently shown a potential developing macro-CT technique structures. This study derived EIT analytical solutions rectangular cement-based samples validated them with experimental data obtained from cubic mortar samples. The validation of the three mathematical functions (Dirac delta, Heaviside step, Gaussian) used as current injection models, Gaussian function produced lowest relative absolute error (4.02%). also explored appropriate setups materials, such Shunt model, flow paths, distribution.

Electrical Impedance Tomography (EIT) is relatively a new imaging technique with which the images of the internal impedance of the region of interest in human body can be constructed effectively without prolonged exposure to radiations. EIT is fast, inexpensive and portable as compared to other imaging techniques. The presented work focuses on construction of human organ images acquired from im...
متن کاملImplementation of Radon Transformation for Electrical Impedance Tomography (EIT)
Radon Transformation is generally used to construct optical image (like CT image) from the projection data in biomedical imaging. In this paper, the concept of Radon Transformation is implemented to reconstruct Electrical Impedance Topographic Image (conductivity or resistivity distribution) of a circular subject. A parallel resistance model of a subject is proposed for Electrical Impedance Top...
متن کاملElectrical Impedance Tomography (EIT) and Its Medical Applications: A Review
This paper reviews the principles of Electrical Impedance Tomography (EIT), different types of current patterns and reconstruction algorithms to assess its potential in medical imaging. A current injection pattern in EIT has its own current distribution profile within the subject under test. Hence, different current patterns have different sensitivity, spatial resolution and distinguishability....
متن کاملElectrical Impedance Tomography (eit) Method for Saturation Determination
3D Electrical Impedance Tomography (EIT) is an alternative to the traditional CT scan technique that has been used to measure saturation distribution within a rock core. The primary motivation for investigating EIT is the applicability to high pressure, high temperature geothermal reservoir conditions, which would require a metal core holder, therefore eliminating the use of the CT scan techniq...
