3D EIT image reconstruction with GREIT.
Most applications of thoracic EIT use a single plane of electrodes on the chest from which a transverse image 'slice' is calculated. However, interpretation of EIT images is made difficult by the large region above and below the electrode plane to which EIT is sensitive. Volumetric EIT images using two (or more) electrode planes should help compensate, but are little used currently. The Graz co...
متن کاملEIT Image Reconstruction by Modified Data
Electrical impedance tomography (EIT) is a radiation-free imaging method. Canonically, in lung EIT, 16 electrodes are placed horizontally on the thorax skin. By injecting currents through electrodes attached to the skin, a set of induced voltage measurements can be collected. The conductivity distribution on the chest plane can be obtained from these electrical boundary conditions. It has been ...
متن کاملA Level Set based Regularization Framework for EIT Image Reconstruction
Electrical Impedance Tomography (EIT) reconstructs the conductivity distribution within a medium from electrical stimulation and measurements at the medium surface. Level set based reconstruction method (LSRM) has gained attention during the last decade as an effective solution to address the need of reconstructing structures with limited amount of available data. The classical LSRM is based on...
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 ...
متن کاملImage Reconstruction using Simulated Annealing Algorithm in EIT
In electrical impedance tomography (EIT), various image reconstruction algorithms have been used in order to compute the internal resistivity distribution of the unknown object with its electric potential data at the boundary. Mathematically, the EIT image reconstruction algorithm is a nonlinear ill-posed inverse problem. This paper presents a simulated annealing technique as a statistical reco...
