EIT reconstruction algorithms: pitfalls, challenges and recent developments.

چکیده
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 suggest common pitfalls or 'inverse crimes' to avoid.

متن کاملA 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...
متن کاملTemporal 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...
متن کاملChoice of reconstructed tissue properties affects interpretation of lung EIT images.
Electrical impedance tomography (EIT) estimates an image of change in electrical properties within a body from stimulations and measurements at surface electrodes. There is significant interest in EIT as a tool to monitor and guide ventilation therapy in mechanically ventilated patients. In lung EIT, the EIT inverse problem is commonly linearized and only changes in electrical properties are re...
متن کاملComparison 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 ...
