EIDORS is an open source software suite for image reconstruction in electrical impedance tomography and diffuse optical tomography, designed to facilitate collaboration, testing and new research in these fields. This paper describes recent work to redesign the software structure in order to simplify its use and provide a uniform interface, permitting easier modification and customization. We de...

In this paper, we 1: announce EIDORS version 3.3, and clarify the new features and changes to the software. Briefly, the new version includes: a) interfaces to FEM generation (distmesh, netgen) and dual model solvers, b) new algorithms (total variation, electrode movement solver, temporal solvers), c) a data repository with in vivo and simulated data and models, d) faster algorithms with better...

MOTIVATION: The accuracy of solutions to partial differential equations (PDE) obtained with the finite element method (FEM) depends on appropriate choice of domain discretization. The elements must be smaller than the smallest features which may occur in the solution. On the other hand, small elements increase the size of the FEM and hence the amount of computational time and memory required to...

In order to apply electrical impedance (EIT), and other modalities, against industrial unit operations it is requisite to employ a sensor architecture which is compliant with the subject process such that it will not detrimentally effect its efficiency nor the integrity of the associated vessel structure. Traditionally symmetrical electrode architectures have been adopted for electrical tomogra...

Electrical Impedance Tomography (EIT) is known as non-invasive method to detect and classify the abnormal breast tissues. Reimaging conductivity distribution within an area of subject reveal tissues inside that area. In this work, we have created a very low-cost system with simple 16-electrode phantom for doing research purposes. The EIT data were measured reconstructed EIDORS software.

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....

The present status of electrical impedance tomography (EIT) is such that many successful laboratory based studies and pilot plant demonstrators are generating interest in developing the technology. However, while the EIT problem is inherently 3D, many studies make 2D assumptions in order to simplify the problem. Proportionately less work has been carried out on the true 3D EIT problem, outside ...
