Thus impedance tomography is an imaging method which may be used to complement x-ray tomography (computer tomography, CT), ultrasound imaging, positron emission tomography (PET), and others. The reader may find more information about the modern medical imaging methods from such references as Krestel (), Webb (), and Wells (). Electrical Impedance Tomography (EIT) is a radiation-free functional modality that enables bedside imaging and monitoring of lung function and by: 5.
Electrical Impedance Tomography (EIT) is a promising application that displays changes in conductivity within a body. The basic principle of the method is the repeated measurement of surface voltages of a body, which are a result of rolling injection of known and small-volume sinusoidal AC current to the body through the electrodes attached to its surface.

Electrical impedance tomography (EIT) uses low-frequency electrical current to probe a body; the method is sensitive to changes in electrical conductivity.
By injecting known amounts of current and measuring the resulting electrical potential field at points on the boundary of the body, it is possible to "invert" such data to determine the conductivity or resistivity of the region of the body probed by the.
Development of an electrical impedance tomograph for complex impedance imaging This project concerns the development of electrical impedance tomography towards the production of complex impedance images.

INTRODUCTION Electrical Impedance Tomography (EIT) is a technique to image the electrical properties within a body using electrical stimulations and measurements applied at electrodes on the body surface.
EIT is useful when the anatomical or physio-logical phenomena of interest create contrasts in File Size: 1MB. With contributions from leading international researchers, Electrical Impedance Tomography: Methods, History and Applications provides an up-to-date review of the progress of EIT, the present state of knowledge, and a look at future advances and applications.
Divided into four parts, the book presents an interdisciplinary approach. Abstract: Electrical impedance tomography (EIT) uses electrical stimulation and measurement at the body surface to image the electrical properties of internal tissues. It has the advantage of noninvasiveness and high temporal resolution but suffers from poor spatial resolution and sensitivity to electrode movement and contact by:.
Electrical impedance tomography (EIT) has been around for some time (the first systems were built in the mid‐s) but is yet to break into mainstream clinical practice. As the editor writes in the introduction, the continuing attraction to EIT seems to come from the fact that “it doesn't clearly work” but “it usually almost works Cited by: 9th World Congress on Industrial Process Tomography Bath, UK SeptemberISBN: 0 5 A1 Multi-modal and multi-spectral methods addressing complex process distributions.
