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.

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 \(\partial\Omega\)

Electrical Impedance Spectroscopy
2018This chapter gives some background on impedance spectroscopy and tissue impedance but also about the instrumentation used for measuring transfer impedance of a biological material under study. The instrumentation concerned here is the current source for applying a current to tissue and the differential amplifier for measuring the resultant voltage.
