    • Advances in nanoparticle‐based medical diagnostic and therapeutic techniques 

      Sardan, Melis; Özkan, Alper Devrim; Zengin, Aygül; Tekinay, Ayşe B.; Güler, Mustafa O. (John Wiley & Sons, 2016-03-11)
      Advances in modern medicine have eliminated several major causes of human mortality and considerably extended life expectancies around the world; however, this increase in the global age average has also boosted the ...
    • Contrast enhancement using phase transition information and total variation 

      Çakır, Serdar; Çetin, A.Enis (Institute of Electrical and Electronics Engineers, 2018)
      Contrast enhancement is an important preprocessing step for the analysis of images. The main aim of contrast enhancement techniques is to increase the visibility of the objects by modifying the spatial characteristics of ...
    • 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 ...
    • In vivo magnetic resonance imaging of mesenchymal stem cells in myocardial infarction 

      Kraitchman, D. L.; Heldman, A. W.; Atalar, E.; Amado, L. C.; Martin, B. J.; Pittenger, M. F.; Hare, J. M.; Bulte, J. W. M. (Lippincott Williams & Wilkins, 2003)
      Background - We investigated the potential of magnetic resonance imaging (MRI) to track magnetically labeled mesenchymal stem cells (MR-MSCs) in a swine myocardial infarction (MI) model. Methods and Results - Adult farm ...
    • Intravascular MR-monitored balloon angioplasty: An in vivo feasibility study 

      Yang, Xiaoming; Bolster Jr., B. D.; Kraitchman, D. L.; Atalar, Ergin (Elsevier Inc., 1998)
      PURPOSE: To develop a new method for monitoring balloon angioplasty by using an intravascular magnetic resonance (MR) imaging technique. MATERIALS AND METHODS: Nine New Zealand White rabbits were used: seven for technique ...
    • A new class of cubic SPIONs as a dual-mode T1 and T2 contrast agent for MRI 

      Alipour, Akbar; Soran-Erdem, Zeliha; Utkur, Mustafa; Sharma, Vijay Kumar; Algın, Oktay; Sarıtaş, Emine Ülkü; Demir, Hilmi Volkan (Elsevier, 2018)
      Superparamagnetic iron oxide nanoparticles (SPIONs) are widely used as a robust negative contrast agent on conventional MRI. In this study, we (a) synthesized a new class of cubic SPIONs as a dual-mode contrast agent in ...
    • Spatial mutual information and PageRank-Based contrast enhancement and Quality-Aware relative contrast measure 

      Celik, T. (Institute of Electrical and Electronics Engineers Inc., 2016)
      This paper proposes a novel algorithm for global contrast enhancement using a new definition of spatial mutual information (SMI) of gray levels of an input image and PageRank algorithm. The gray levels are used to represent ...
    • System for MR image-guided prostate interventions: Canine study 

      Susil, R. C.; Krieger, A.; Derbyshire, J. A.; Tanacs, A.; Whitcomb, L. L.; Fichtinger, G.; Atalar, E. (Radiological Society of North America, Inc.Radiological Society of North America, Inc., 2003)
      The purpose of this study was to demonstrate the use of a transrectal system that enables precise magnetic resonance (MR) image guidance and monitoring of prostate interventions. The system used a closed-bore 1.5-T MR ...
