Electrical impedance tomography to measure lung ventilation distribution in healthy horses and horses with left‐sided cardiac volume overload

open access: yesJournal of Veterinary Internal Medicine, Volume 35, Issue 5, Page 2511-2523, September/October 2021., 2021
Abstract Background Left‐sided cardiac volume overload (LCVO) can cause fluid accumulation in lung tissue changing the distribution of ventilation, which can be evaluated by electrical impedance tomography (EIT). Objectives To describe and compare EIT variables in horses with naturally occurring compensated and decompensated LCVO and compare them to a ...

EIT's teething problems [PDF]

open access: yesScience, 2016
Good policy intentions do not always translate into the desired outcome. Nearly a decade ago, the European Commission (EC) launched two new entities with the goal of building a European-wide ecosystem—one to support frontier research, the European Research Council (ERC), and the other to boost innovation, the European Institute of Technology (EIT ...

Estimating regional pulmonary blood flow in EIT with regularized deconvolution with a Tikhonov regularization

open access: yesCurrent Directions in Biomedical Engineering, 2020
Electrical Impedance Tomography (EIT) is a clinically used tool for bed-side monitoring of ventilation. Previous work also showed a high potential for lung perfusion monitoring with indicator-enhanced EIT.

Probing deep lung regions using a new 6-electrode tetrapolar impedance method

open access: yesJournal of Electrical Bioimpedance, 2023
Probing deep regions of the lung using electrical impedance is very important considering the need for a low cost and simple technique, particularly for the low and medium income countries.

Objective selection of hyperparameter for EIT [PDF]

open access: yesPhysiological Measurement, 2006
An algorithm for objectively calculating the hyperparameter for linearized one-step electrical impedance tomography (EIT) image reconstruction algorithms is proposed and compared to existing strategies. EIT is an ill-conditioned problem in which regularization is used to calculate a stable and accurate solution by incorporating some form of prior ...

Quality of Service (QoS) improving schemes in optical networks

open access: yesHeliyon, 2020
In optical networks, such as OPS/OBS, the network results into significant loss in the network layer. When the loss significantly deteriorates the QoS by increasing the Bit Error Rate (BER), a viable approach can be used to increase the performance. This

Evaluation of EIT system performance [PDF]

open access: yesPhysiological Measurement, 2011
An electrical impedance tomography (EIT) system images internal conductivity from surface electrical stimulation and measurement. Such systems necessarily comprise multiple design choices from cables and hardware design to calibration and image reconstruction.
