Electrode positions and current patterns for 3D EIT
نویسندگان
چکیده
For a 3D electrical impedance tomography (EIT) system, it is necessary to improve electrode geometries placed around a body surface, and correspondingly apply stimulation and measurement patterns to produce maximum distinguishability. Advanced EIT image reconstruction requires designing systems with the electrode geometry and current injection such that the full ensemble of measurements provides as high SNR as possible over all of the volume under investigation not only for over a certain region of interest. A 3D two-electrode plane simulation study is undertaken using 7 electrode geometries and 16 different stimulation and measurement patterns for each electrode geometry. The simulation results show that several electrode geometries and current patterns produced promising results with the high distinguishability which can subsequently lead to improved image reconstruction.

Optimized electrode positions and stimulation patterns in head EIT
Electrical Impedance Tomography (EIT) has potential for imaging of the head to image cerebral edema and stroke, and to assist the EEG inverse problem. One key challenge is the low distinguishability of head EIT. In this paper, we develop a strategy to improve distinguishability by optimizing electrode configurations and stimulation and measurement patterns. In a hemispherical simulation phantom...
متن کاملEffective electrode positions and stimulation patterns for head EIT
The objective of this study is to find an effective stimulation and measurement strategy to improve distinguishability for head EIT. To better understand the relationship between distinguishability and various strategies (stimulation/measurement patterns) for a set of electrodes, we evaluated a realistic head model and a range of common strategies.

Electrical impedance tomography (EIT) is a promising medical imaging technique which could aid differentiation of haemorrhagic from ischaemic stroke in an ambulance. One challenge in EIT is the ill-posed nature of the image reconstruction, i.e., that small measurement or modelling errors can result in large image artefacts. It is therefore important that reconstruction algorithms are improved w...

Electrical impedance tomography (EIT) uses body surface electrical stimulation and measurements to create conductivity images; it shows promise as a non-invasive technology to monitor the distribution of lung ventilation. Most applications of EIT have placed electrodes in a 2D ring around the thorax, and thus produced 2D cross-sectional images. These images are unable to distinguish out-of-plan...

We characterize the ability of electrical impedance tomography (EIT) to distinguish changes in internal conductivity distributions, and analyze it as a function of stimulation and measurement patterns. A distinguishability measure, z, is proposed which is related to the signal-to-noise ratio of a medium and to the probability of detection of conductivity changes in a region of interest. z is a ...
