Electrical Impedance Tomography
Current Opinion in Critical Care, 2009Electrical impedance tomography (EIT) is a noninvasive, radiation-free monitoring tool that allows real-time imaging of ventilation. The purpose of this article is to discuss the fundamentals of EIT and to review the use of EIT in critical care patients.In addition to its established role in describing the distribution of alveolar ventilation, EIT has ...

Electrical Impedance Tomography
SIAM Review, 1999A mathematical model for electrical impedance tomography is described. This model is used for explaining the Rensselaer system. Some reconstruction algorithms are surveyed, especially the Moser algorithm. Some experimental tests are given.

Multifrequency electrical impedance tomography
Clinical Physics and Physiological Measurement, 1992Multifrequency tomography may be conveniently achieved by sequentially sweeping the probing drive current and measuring the resultant voltages at each frequency. If events change during measurement comparisons between frequencies cannot be made. Mixing several frequency components may decrease acquisition time but increase the complexity of the ...

BIOIMPEDANCE TOMOGRAPHY (ELECTRICAL IMPEDANCE TOMOGRAPHY)
Annual Review of Biomedical Engineering, 2006Electrical impedance tomography (EIT) is a relatively new imaging method that has evolved over the past 20 years. It has the potential to be of great value in clinical diagnosis; however, EIT is a technically difficult problem to solve in terms of developing hardware for data capture and the algorithms to reconstruct the images.

Electrical impedance tomography
IEEE Signal Processing Magazine, 2001Electrical impedance tomography (EIT) is an imaging modality that estimates the electrical properties at the interior of an object from measurements made on its surface. Typically, currents are injected into the object through electrodes placed on its surface, and the resulting electrode voltages are measured.

Magnetic Resonance Electrical Impedance Tomography
2022Magnetic Resonance Electrical Impedance Tomography (MREIT) is a high-resolution bioimpedance imaging technique that has developed over a period beginning in the early 1990s to measure low-frequency (

Electrical Impedance Tomography
2017Presently, non-invasive techniques are in vogue and preferred standard clinical approach because of its limitless advantages in monitoring real time phenomenon occurring within our human body without much interference. Many techniques such as ultrasound, magnetocardiography, CT scan, MRI etc., are used for real time monitoring but are generally not ...

Electrical impedance tomography
Inverse Problems, 2002Updated (up to 2002, 153 references) theoretical and numerical studies of the inverse problem for the continuum model of EIT which seeks the admittivity \((\gamma(x)= \sigma(x)+ i\omega\varepsilon(x))\) inside a body \(\Omega\) from the knowledge of the Dirichlet to Neumann (DtN) (or the Neumann to Dirichlet (NtD)) map at the boundary \(\partial\Omega\)
