چکیده

We review developments, issues and challenges in Electrical Impedance Tomography (EIT), for the 4th Workshop on Biomedical Applications of EIT, Manchester 2003. We focus on the necessity for three dimensional data collection and reconstruction, efficient solution of the forward problem and present and future reconstruction algorithms. We also suggest common pitfalls or “inverse crimes” to avoid.

EIT reconstruction algorithms: pitfalls, challenges and recent developments.

We review developments, issues and challenges in electrical impedance tomography (EIT) for the 4th Conference on Biomedical Applications of Electrical Impedance Tomography, held at Manchester in 2003. We focus on the necessity for three-dimensional data collection and reconstruction, efficient solution of the forward problem, and both present and future reconstruction algorithms. We also sugges...

A Primal Dual Interior Point Framework for EIT Reconstruction with Automatic Regularization

The spatial resolution of the reconstructed images in Electrical impedance tomography (EIT) is low and a priori information regarding smooth conductivity changes limits reconstruction of sharp images while it is preferred in order to differentiate tissue boundaries in medical imaging. Measurement errors are another barrier that hinder a good image reconstruction. Generally `2 norms have been us...

Temporal effects in EIT image reconstructions

Most EIT image reconstruction algorithms do not account for temporal effects such as non-instantaneous acquisition of data frames and temporal correlation between successive EIT images. We have recently published a framework for assessing the performance of reconstruction algorithms accounting for temporal effects. Results of applying this framework to five reconstruction algorithms and three t...

Comparison of Image Reconstruction Algorithms in EIT Imaging

Electrical Impedance Tomography (EIT) is a medical imaging technique which can be used to monitor the regional ventilation in patients utilizing voltage measurements made at the thorax. Several reconstruction algorithms have been developed during the last few years. In this manuscript we compare a well-established algorithm and a recently developed method for image reconstruction regarding EIT ...

Comparison of 3D Image Reconstruction Techniques using Real Electrical Impedance Measurement Data

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 ...
