Electrical impedance imaging allows functional images to be produced at low cost, high speed, and no hazard to the patient. The system developed uses 16 electrodes placed around the thorax. The technique of Applied Potential Tomography (APT) described by the authors produces tomographic images of resistivity changes from data collected at 24 frames/s. The spatial resolution and sensitivity are sufficient to image lung ventilation and the movement of blood during the cardiac cycle. As blood has a relatively low resistivity, the two ventricles are imaged as areas of increased resistivity and the lungs as areas of decreased resistivity on systole.

Electrical impedance tomography: Induced-current imaging achieved with a multiple coil system Gençer, Nevzat Güneri; Williamson, SJ (1996-02-01) An experimental study of induced-current electrical impedance tomography verifies that image quality Is enhanced by employing six rather than three induction coils by increasing the number of independent measurements. However, with an increasing number of coils, the inverse problem becomes more sensitive to measurement noise, Using 16 electrodes to measure surface voltages, it Is possible to collect 6 x 15 = 90 independent measurements. For comparison purposes, images of two dimensional conductivity perturb...
Current constrained voltage scaled reconstruction (CCVSR) algorithm for MR-EIT and its performance with different probing current patterns Birgul, O; Eyüboğlu, Behçet Murat; Ider, YZ (IOP Publishing, 2003-03-07) Conventional injected-current electrical impedance tomography (EIT) and magnetic resonance imaging (MRI) techniques can be combined to reconstruct high resolution true conductivity images. The magnetic flux density distribution generated by the internal current density distribution is extracted from MR phase images. This information is used to form a fine detailed conductivity image using an Ohm's law based update equation. The reconstructed conductivity image is assumed to differ from the true image by a s...
ELECTRICAL-IMPEDANCE TOMOGRAPHY USING INDUCED CURRENTS Gençer, Nevzat Güneri; Kuzuoğlu, Mustafa (1994-06-01) The mathematical basis of a new imaging modality, Induced Current Electrical Impedance Tomography (EIT), is investigated. The ultimate aim of this technique is the reconstruction of conductivity distribution of the human body, from voltage measurements made between electrodes placed on the surface, when currents are induced inside the body by applied time varying magnetic fields. In this study the two-dimensional problem is analyzed. A specific 9-coil system for generating nine different exciting magnetic f...
Electrical Impedance Tomography Induced Current Gençer, Nevzat Güneri (2006-01-01) The ultimate goal of induced‐current electrical impedance tomography (ICEIT) is to image the electrical impedance distribution within the human body. In ICEIT, time‐varying magnetic fields are applied to induce currents in the body and surface voltage measurements are used to reconstruct impedance distribution. Time‐varying fields are usually generated by sinusoidal current‐carrying wires encircling the conducting body. Given the conductivity distribution, calculating the surface voltages due a given coil c...
Induced Current Magnetic Resonance Electrical Impedance Tomography with z-Gradient Coil Eroglu, Hasan H.; Eyuboglu, Murat (2014-08-30) Magnetic Resonance Electrical Impedance Tomography (MREIT) is a medical imaging method that provides images of electrical conductivity at low frequencies (0-1 kHz). In MREIT, electrical current is applied to the body via surface electrodes and corresponding magnetic flux density is measured by means of Magnetic Resonance (MR) phase imaging techniques. By utilizing the magnetic flux density measurements and surface potential measurements images of true conductivity distribution can be reconstructed. In order...
