Magnetic Resonance Electrical Impedance Tomography (MREIT) reconstructs true conductivity images by using current density distribution and surface potential measurements. In this study, equipotential projection [1] and J-substitution image reconstruction [2] algorithms for MREIT are compared. A novel reconstruction method, J-substitution and filtered equipotential-projection based hybrid reconstruction algorithm, is proposed. In this method, the image reconstructed with equipotential projection algorithm is filtered and then assigned as the starting conductivity distribution for J-substitution algorithm. True conductivity distribution can also be reconstructed with two surface potential measurements. Methods are simulated on a thorax phantom and results show that the proposed method has an improved performance in some regions.

Anisotropic Conductivity Imaging with MREIT Using J-substitution and Hybrid J-substitution Algorithms
Degirmenci, E.; Eyüboğlu, Behçet Murat (2009-09-12)
Magnetic Resonance Electrical Impedance Tomography (MREIT) is a tomographical imaging technique which uses measurements of magnetic flux density induced by a probing current to reconstruct electrical conductivity distribution within a conductor object with magnetic resonance active nuclei. In this study, two novel anisotropic conductivity reconstruction algorithms for MREIT are proposed. The technique is evaluated with simulated measurements.
Equipotential projection based MREIT reconstruction without potential measurements
Eyüboğlu, Behçet Murat (2007-09-02)
Magnetic resonance electrical impedance tomography (MREIT) is used to produce high resolution images of true conductivitv distribution. Images are reconstructed by utilising measurements of magnetic flux density distribution and surface potentials. Surface potential measurements are needed to reconstruct true conductivity values. In this study, a novel MREIT reconstruction algorithm is developed to generate conductivity images without utilizing the surface potential measurements. The proposed algorithm and ...
J-based Magnetic Resonance Conductivity Tensor Imaging (MRCTI) at 3 T
Sadighi, M.; Goksu, C.; Eyüboğlu, Behçet Murat (2014-08-30)
In this study, current density (J) - based Magnetic Resonance Conductivity Tensor Imaging (MRCTI) reconstruction algorithms namely, the Anisotropic Equipotential Projection (AEPP), the Anisotropic J-Substitution (AJS) and the Anisotropic Hybrid J-Substitution (AHJS) algorithms are implemented to reconstruct conductivity tensor images of a physical phantom using a 3T magnetic resonance imaging system. 10mA current pulses are injected in synchrony with a conventional spin-echo pulse sequence. Furthermore, a n...
Magnetic Resonance Electrical Impedance Tomography For Anisotropic Conductivity Imaging
Degirmenci, E.; Eyüboğlu, Behçet Murat (2008-11-27)
Magnetic Resonance Electrical Impedance Tomography (MREIT) brings high resolution imaging of true conductivity distribution to reality. MREIT images are reconstructed based on measurements of current density distribution and a surface potential value, induced by an externally applied current flow. Since biological tissues may be anisotropic, isotropic conductivity assumption, as it is adopted in most of MREIT reconstruction algorithms, introduces reconstruction inaccuracy. In this study, a novel algorithm i...

DEĞİRMENCİ, EVREN; Eyüboğlu, Behçet Murat (2007-09-02)
Magnetic resonance electrical impedance tomography (MREIT) is a new medical imaging technique which combines boundary potential measurements of electrical impedance tomography (EIT) and internal current density distribution obtained from magnetic resonance imaging (MRI) to produce conductivity images having high spatial resolution and accuracy. In this study, a novel method of reconstructing images of anisotropic conductivity tensor distribution inside an electrically conducting subject is proposed for MREI...
