Current constrained voltage scaled reconstruction (CCVSR) algorithm for MR-EIT and its performance with different probing current patterns
Birgül, Ö.; Eyüboğlu, B. M.; İder, Y. Z. (Institute of Physics Publishing, 2003)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 of aortic mechanical prosthetic valve closure sound model parameters on the surface of the chest
Baykal, A.; İder, Y. Z.; Köymen, Hayrettin (Institute of Electrical and Electronics Engineers, 1995-04)It has been previously proposed that heart valve closure sounds can be modeled by a sum of decaying sinusoids, based on the hypothesis that the heart cavity, heart walls, major vessels, and other structures in the chest ... -
Experimental results for 2D magnetic resonance electrical impedance tomography (MR-EIT) using magnetic flux density in one direction
Birgül, Ö.; Eyüboğlu, B. M.; İder, Y. Z. (Institute of Physics Publishing, 2003)Magnetic resonance electrical impedance tomography (MR-EIT) is an emerging imaging technique that reconstructs conductivity images using magnetic flux density measurements acquired employing MRI together with conventional ... -
Induced current magnetic resonance-electrical impedance tomography
Özparlak, L.; İder, Y. Z. (Institute of Physics, 2005)Magnetic resonance-electrical impedance tomography (MR-EIT) is a conductivity imaging method based on injecting currents into the object. In this study, a new MR-EIT method, whereby currents are induced inside the object ... -
A Spectrally efficient PMR system utilizing broadcast service
Sengül, E.; Köymen, Hayrettin; İder, Y. Z. (Institute of Electrical and Electronics Engineers, 2005)Different trunked Private Mobile Radio (PMR) systems have been designed over the last several decades, all of which have symmetric downlink and uplink channel capacities. Due to this symmetry, these systems may not be ... -
Uniqueness and reconstruction in magnetic resonance-electrical impedance tomography (MR-EIT)
İder, Y. Z.; Onart, S.; Lionheart, W. R. B. (Institute of Physics Publishing, 2003)Magnetic resonance-electrical impedance tomography (MR-EIT) was first proposed in 1992. Since then various reconstruction algorithms have been suggested and applied. These algorithms use peripheral voltage measurements and ...
