In this study, recently proposed diffusion tensor magnetic resonance electrical impedance tomography (DT-MREIT) is compared with magneticresonance conductivity tensor imaging (MRCTI) using simulated measurements generated by means of a finite element model. Both methods areused to reconstruct conductivity tensor images of an anisotropic conductivity distribution. In DT-MREIT, extra cellular conductivity and diffusivityratio (ECDR) is recovered from its transverse gradient. In MRCTI, the conductivity tensor is reconstructed from two current profiles by usinganisotropic B sensitivity (AB S) method with a stronger regularization. Reconstructed conductivity images suggest that MRCTI provides betteraccuracy than DT-MREIT, at lower SNR levels.

Single Current Diffusion Tensor Magnetic Resonance Electrical Impedance Tomography: A Simulation Study
Sadighi, Mehdi; Şişman, Mert; Açıkgöz, Berk Can; Eyüboğlu, Behçet Murat (2020-08-08)
Diffusion Tensor Magnetic Resonance Electrical Impedance Tomography (DT-MREIT) is an imaging technique providing low-frequency conductivity tensor images. In all DT-MREIT applications in the literature two linearly independent current injection patterns are used to reconstruct the extra-cellular conductivity and diffusivity ratio () which is the space-dependent scale factor between and in a porous medium. In this study, a new approach is proposed to reconstruct using only one current injection pattern. The ...
Equipotential projection based magnetic resonance electrical impedance tomography (mr-eit) for high resolution conductivity imaging
Özdemir, Mahir Sinan; Eyüboğlu, Behçet Murat; Department of Electrical and Electronics Engineering (2003)
In this study, a direct reconstruction algorithm for Magnetic Resonance Electrical Impedance Tomography (MR-EIT) is proposed and experimentally implemented for high resolution true conductivity imaging. In MR-EIT, elec trical impedance tomography (EIT) and magnetic resonance imaging (MRI) are combined together. Current density measurements are obtained making use of Magnetic Resonance Current Density Imaging (MR-CDI) techniques and peripheral potential measurements are determined using conventional EIT tech...
Magnetic resonance current density imaging using one component of magnetic flux density
Ersöz, Ali; Eyüboğlu, Behçet Murat; Department of Electrical and Electronics Engineering (2010)
Magnetic Resonance Electrical Impedance Tomography (MREIT) algorithms using current density distribution have been proposed in the literature. The current density distribution can be determined by using Magnetic Resonance Current Density Imaging (MRCDI) technique. In MRCDI technique, all three components of magnetic flux density should be measured. Hence, object should be rotated inside the magnet which is not trivial even for small size objects and remains as a strong limitation to clinical applicability o...
An array of square plate resonators with adjustable resonance frequency
Polat, Halim; Azgın, Kıvanç; Department of Mechanical Engineering (2022-8-19)
In this study, a MEMS square plate resonator with adjustable resonance frequency is designed, mathematically modelled and verified with finite element analysis (FEA) and experiments. Resonance frequency of microelectromechanical system (MEMS) square plate is adjusted with the help of several cutouts which are placed in unique lines like center lines and nodal lines. First of all, plates are modelled with the help of semi-analytic method called Rayleigh-Ritz method for the 1st and 2nd modes since higher mode...
Implementation and comparison of reconstruction algorithms for magnetic resonance-electric impedance tomography (mr-eit)
Martin Lorca, Dario; Eyüboğlu, Behçet Murat; Department of Biomedical Engineering (2007)
In magnetic resonance electrical impedance tomography (MR-EIT), crosssectional images of a conductivity distribution are reconstructed. When current is injected to a conductor, it generates a magnetic field, which can be measured by a magnetic resonance imaging (MRI) scanner. MR-EIT reconstruction algorithms can be grouped into two: current density based reconstruction algorithms (Type-I) and magnetic flux density based reconstruction algorithms (Type-II). The aim of this study is to implement a series of r...
