An Effective Measured Data Preprocessing Method in Electrical Impedance Tomography
As an advanced process detection technology, electrical impedance tomography (EIT) has widely been paid attention to and studied in the industrial fields. But the EIT techniques are greatly limited to the low spatial resolutions. This problem may result from the incorrect preprocessing of measuring data and lack of general criterion to evaluate different preprocessing processes. In this paper, ...
متن کاملApplications of Electrical Impedance Tomography in Neurology
Introduction: Electrical impedance tomography (EIT) is a non-invasive technique utilized in various medical applications, including brain imaging and other neurological diseases. Recognizing the physiological and anatomical characteristics of organs based on their electrical properties is one of the main applications of EIT, as each variety of tissue structure has its own electrical characteris...
متن کاملSystolic Time Intervals Measured by Electrical Impedance Tomography (EIT)
Electrical Impedance Tomography (EIT) is a non-invasive and low-cost functional imaging technique that measures thoracic impedance. Until now, it was primarily used to reveal respirationrelated changes in the lungs. However, recent work has shown the feasibility of using this technology to monitor hemodynamic parameters. In particular, mean arterial blood pressure can be estimated via EIT, give...
متن کاملAn Introduction to Electrical Impedance Tomography
The inverse problem of Electrical Impedance Tomography (EIT) is that of imaging a spatially varying, complex admittivity function γ(x, ω) in a domain Ω ⊂ I R (n = 2 or 3), given measurements of low frequency ω alternating electrical currents and potentials at the boundary ∂Ω. The real and imaginary parts of admittivity γ(x, ω) are the electrical conductivity σ(x) and ω (x), respectively, where ...
متن کاملElectrical impedance tomography
We review theoretical and numerical studies of the inverse problem of electrical impedance tomography which seeks the electrical conductivity and permittivity inside a body, given simultaneous measurements of electrical currents and potentials at the boundary.
