Coded scenes for fast system calibration in magnetic particle imaging
Ilbey, S.; Top, C. B.; Güngör, A.; Sarıtaş, Emine Ülkü; Güven, E. (IEEE, 2018)Magnetic nanoparticle (MNP) agents have a wide range of clinical application areas for both imaging and therapy. MNP distribution inside the body can be imaged using Magnetic Particle Imaging (MPI). For MPI image reconstruction ... -
Comparison of system-matrix-based and projection-based reconstructions for field free line magnetic particle imaging
Ilbey, S.; Top, C. B.; Güngör, A.; Çukur, Tolga; Sarıtaş, Emine Ülkü; Güven, H. E. (Infinite Science Publishing, 2017)In magnetic particle imaging (MPI), system sensitivity can be enhanced by scanning the sample along a field free line (FFL) instead of a field free point (FFP). FFL MPI data can then be processed via system-matrix or ... -
Compressed multi-contrast magnetic resonance image reconstruction using Augmented Lagrangian Method
Güngör, A.; Kopanoğlu, E.; Çukur, Tolga; Güven, H. E. (IEEE, 2016)In this paper, a Multi-Channel/Multi-Contrast image reconstruction algorithm is proposed. The method, which is based on the Augmented Lagrangian Method uses joint convex objective functions to utilize the mutual information ... -
Joint dictionary learning reconstruction of compressed multi-contrast magnetic resonance imaging
Güngör, A.; Kopanoğlu, E.; Çukur, Tolga; Güven, E.; Yarman-Vural, F. T. (Institute of Electrical and Electronics Engineers, 2018)This study deals with reconstruction of compressed multicontrast magnetic resonance image (MRI) reconstruction using joint dictionary learning. Usually pre-determined dictionaries are used for compressed sensing reconstructions. ... -
Real-time three-dimensional image reconstruction using alternating direction method of multipliers for magnetic particle imaging
İlbey, Serhat; Güngör, A.; Top, C. B.; Sarıtaş, Emine Ülkü; Güven, H. E. (IEEE, 2018)Manyetik Parçacık Görüntüleme (MPG), süperparamanyetik demiroksit nanoparçacıklarının uzamsal dağılımını tespit etmekte kullanılan görece yeni bir medikal görüntüleme yöntemidir. MPG’de görüntü geriçatımı için kullanılan ... -
Simulation of a digital communication system
Güngör, A.; Arıkan, F.; Arıkan, Orhan (IEEE, 2005-09)In this paper, basic components of a digital communication system are simulated by a computer program. The simulation program is modular and flexible to incorporate any future additions and updates. The simulation program ... -
Synthesis of a novel poly(arylene ether ketone) and its conducting composites with polypyrrole
Selampinar, F.; Akbulut, U.; Yildiz, E.; Güngör, A.; Toppare, L. (Elsevier, 1997)The synthesis of a 1,3-bis(4-fluorobenzoyl)-5-tert-butyl benzene and hexafluoro bisphenol A based poly(arylene ether ketone) (PEK) was described. The electrically conductive composites of polypyrrole (PPy) and PEK were ... -
A synthesis-based approach to compressive multi-contrast magnetic resonance imaging
Güngör, A.; Kopanoğlu, E.; Çukur, Tolga; Güven, H. E. (IEEE, 2017)In this study, we deal with the problem of image reconstruction from compressive measurements of multi-contrast magnetic resonance imaging (MRI). We propose a synthesis based approach for image reconstruction to better ...
