In Electrical Impedance Tomography (EIT). the main goal is to reconstruct the conductivity distribution of an object by means of repeated current injection through neighboring electrodes and measuring the resulting voltage differences between the remaining electrodes. Most of the algorithms currently used in EIT reconstruct the conductivity variation after the problem is linearized around a known conductivity distribution. In this new algorithm, variational techniques will be used to obtain a set of equations that must be satisfied by the optimum conductivity distribution, namely the state and adjoint state (or, costate) equations and the expression which is obtained by evaluating the gradient of the cost functional with respect to the conductivity distribution.

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...
Design and Assembly of a Static Magnetic Field Generator for Lorentz Field Electrical Impedance Tomography Tetik, Ahmet Onder; Ghalichi, Elyar; Kaboutari, Keivan; Gençer, Nevzat Güneri (2016-01-01) In Lorentz Field Electrical Impedance Tomography (LFEIT), ultrasound waves are transmitted to a tissue under static magnetic field. Magnetic fields of currents generated in boundaries where conductivity difference exists because of vibrations are measured with coils. In this study, a static magnetic field is created with permanent magnets and magnetic core for LFEIT. The contribution of magnetic core to the created magnetic flux density is demonstrated. Based on these simulation studies magnetic core is des...
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...
A New approach for distributed amplifier design Yılmaz, İsmail Gökhan; Koç, Seyit Sencer; Demir, Şimşek; Department of Electrical and Electronics Engineering (2012) In this thesis work, a new distributed amplifier topology is discussed and applied to three different cases. The topology is based on dividing the frequency spectrum into channels and amplifying afterwards. The channelized and amplified signals are then combined at the output for broadband amplification. This topology is used in the design of a three channel 0.1-1 GHz amplifier with a gain of 14.5±0.6 dB. The design is fabricated, and then the measured and simulated results are compared. A second 0.1-1 GHz ...
ELECTRICAL-IMPEDANCE TOMOGRAPHY OF TRANSLATIONALLY UNIFORM CYLINDRICAL OBJECTS WITH GENERAL CROSS-SECTIONAL BOUNDARIES IDER, YZ; Gençer, Nevzat Güneri; ATALAR, E; TOSUN, H (1990-03-01) An algorithm is developed for electrical impedance tomography (EIT) of finite cylinders with general cross-sectional boundaries and translationally uniform conductivity distributions. The electrodes for data collection are assumed to be placed around a crosssectional plane; therefore the axial variation of the boundary conditions and also the potential field are expanded in Fourier series. For each Fourier component a two-dimensional (2-D) partial differential equation is derived. Thus the 3-D forward probl...
