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...

In this study, a hp-version of Finite Element Method (FEM) was applied for forward modeling in image reconstruction of Electrical Impedance Tomography (EIT). The EIT forward solver is normally based on the conventional Finite Element Method (h-FEM). In h-FEM, the polynomial order (p) of the element shape functions is constant and the element size (h) is decreasing. To have an accurate simulatio...

<span>Bone fractures can result in accidents, osteoporosis, bone cancer, or other conditions. X-Ray is a medical imaging technique often used to detect fractures. However, X-Rays have radiation effects that harm patients, health workers, and the environment. Electrical impedance tomography (EIT) system obtain object images based on electrical distribution. In fractures, proximal tissue ex...

in this study, focuses on applying the hp-version for forward modeling. the eit forward solver is normally based on the conventional finite element method (hfem). in h-fem, the polynomial order p of the element shape functions is constant and the element size h, is decreased. to accurately simulate the forward solution with the hfem, a mesh with large number of nodes and elements is usually need...

Plant phenotyping plays an important role for the thorough assessment of plant traits such as growth, development, and physiological processes with target achieving higher crop yields by proper management. The can be done utilizing two- three-dimensional image reconstructions inhomogeneities. quality reconstructed is required to maintain a high accuracy good resolution, it desirable reconstruct...

Electrical impedance tomography (EIT) is a soft field tomography modality based on the application of electric current to a body and measurement of voltages through electrodes at the boundary. The interior conductivity is reconstructed on a discrete representation of the domain using a finite-element method (FEM) mesh and a parametrization of that domain. The reconstruction requires a sequence ...

MOTIVATION: In lung EIT, the quantity of interest is the change in regional air volume in the lungs. However, the actual quantity reconstructed is change in a bulk electrical property, usually conductivity, which is not always easy to interpret. In this study, we investigate how the choice of the reconstructed physical quantity affects the properties of the sensitivity matrix and images obtaine...
