Imaging the complex impedance in electrical impedance tomography
Clinical Physics and Physiological Measurement, 1992Measuring the reactive component of the bio-impedance enables a full characterisation of the frequency response of a tissue. The amplitude of the reactive component is relatively small in the frequency range generally used in electrical impedance tomography (EIT). Its measurement is therefore more sensitive to errors.

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.

A phantom for electrical impedance tomography
Clinical Physics and Physiological Measurement, 1988A method has been developed for constructing phantoms for electrical impedance tomography (EIT). A mesh of resistors is soldered to pins in a matrix board and forms a physical realisation of a finite element numerical model. To simulate different body tissues, changes in the apparent electrical conductivity and permittivity can be introduced at a ...

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 \(\partial\Omega\)

Biomedical applications of electrical impedance tomography
Physiological Measurement, 2004The interdisciplinary nature of biomedical applications of electrical impedance tomography (EIT) sets many challenges that require an integrated approach to problem solving. This issue of Physiological Measurement follows a tradition of special issues on EIT, providing the opportunity for mathematicians, engineers, physicists and clinicians to present ...
