  • Advanced computational tools for real-time MR imaging 
    Saybaşılı, Haris. (Thesis (Ph.D.)-Bogazici University. Institute of Biomedical Engineering, 2009., 2009.)
    Real-time Magnetic Resonance Imaging (MRI) has the potential of successfully guiding interventional applications. Overall, the requirements of real-time MRI can be categorized as: (i) fast data acquisition, (ii) fast image ...
  • An optoelectronic system for device localization in interventional MRI 
    Tümer, Murat. (Thesis (Ph.D.)-Bogazici University. Institute of Biomedical Engineering, 2015., 2015.)
    In active catheter tracking, a microcoil directly connected to the MRI system and positioned at the distal end of the catheter is employed for localization. The peaks in the frequency spectrum of the acquired MR signal ...
  • Clinical grade active guidewire and catheter for interventional cardiovascular MRI 
    Kocatürk, Özgür. (Thesis (Ph.D.)-Bogazici University. Institute of Biomedical Engineering, 2009., 2009.)
    The success and safety of interventional magnetic resonance imaging (MRI) procedures requires conspicuous intravascular instruments that can be distinguished from surrounding tissues. In this dissertation work, an "active" ...
  • Customizable TDI-based whole body X-ray scanner 
    Durmaz, Fevzi Aytaç. (Thesis (Ph.D.)-Bogazici University. Institute of Biomedical Engineering, 2020., 2020.)
    Medical X-ray systems are the gold standard in certain cases of medical diagnostics for over 100 years. The main scope of our studies is to develop a new full-body X-ray scanner device using line scanner detectors, and a ...
  • Design and application of compartmentalized platforms for neurobiological research 
    Çetinkaya Fışgın, Aysel. (Thesis (Ph.D.)-Bogazici University. Institute of Biomedical Engineering, 2016., 2016.)
    Conventional culture systems remain inadequate for comprehensive understanding of injury and regeneration in peripheral neurons that extend axons over long distances and through varying extracellular microenvironments. ...
  • Detailed analysis of voxel based morphometry 
    Okur, Özlem Özmen. (Thesis (Ph.D.)-Bogazici University. Institute of Biomedical Engineering, 2016., 2016.)
    Voxel Based Morphometry, VBM, is one of the most widely used brain morphometry methods which aims to reveal the structural differences between the brain MR images of different populations. It is a whole brain and fully ...
  • Development of a modular software platform for digital X-ray systems 
    Brusan, Altay. (Thesis (Ph.D.)-Bogazici University. Institute of Biomedical Engineering, 2020., 2020.)
    Health centers require full-body X-ray imaging in their busy trauma departments. Full-body X-ray scans are required for bone examinations such as diagnosis of osteoarthritis and degenerative changes in the lumbar spine. ...
  • Improvement of ASL basd MR angiography for novel applications 
    Özyurt, Onur. (Thesis (Ph.D.)-Bogazici University. Institute of Biomedical Engineering, 2017., 2017.)
    In this study, a custom four dimensional arterial spin labeling angiography (4D ASL) sequence and a proof-of-concept software tool to integrate 4D ASL data to routine scanning were implemented. One of the aims of this study ...
  • MRI assessment of in vivo epimuscular myofascial force transmission 
    Yaman, Alper. (Thesis (Ph.D.)-Bogazici University. Institute of Biomedical Engineering, 2014., 2014.)
    Recent developments have been evolving magnetic resonance imaging (MRI) to a combined tool in order to assess human anatomy and physiology in vivo. In the present thesis 3D high resolution anatomic and di usion weighted ...
  • Multimodal investigation of fMRI and fNIRS derived breath hold BOLD signals with an expanded balloon model 
    Emir, Uzay Emrah. (Thesis (Ph.D.)-Bogazici University. Institute of Biomedical Engineering, 2008., 2008.)
    Multimodal investigation of blood oxygenation level-dependent (BOLD) signal, using both functional near infrared spectroscopy (fNIRS) and functional magnetic resonance imaging (fMRI), may give further insight to the ...
  • Revealing gene interactions using Bayesian Networks 
    İşçi, Şenol. (Thesis (Ph.D.)-Bogazici University. Institute of Biomedical Engineering, 2012., 2013.)
    High throughput biological data (HTBD) targeting understanding of biochemical interactions in the cell can best be analyzed, and explained within the context of networks and pathways. Such data generally represents stochastic ...
