  • Data augmentation on chest x-rays for improving pathology classification performance 
    Adıgüzel, Onur. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2022., 2022)
    In recent years, deep learning techniques have made great progress. We can see applications of it in many fields such as economics, military, healthcare, and so on. Healthcare, in particular, is one of the most critical ...
  • Design of a wide range kVp-meter 
    Tümer, Murat. (Thesis (M.S.)-Bogazici University. Institute of Biomedical Engineering, 2007., 2007.)
    The kVp setting is one of the major factors affecting the image quality in X-ray imaging and should be annually measured and calibrated if necessary. In this thesis, a kVp-meter is designed and a prototype unit was built ...
  • Development of an acqusition and image enhancement platform for digital dental imaging 
    Yazıcı, Abdulkadir. (Thesis (M.S.) - Bogazici University. Institute of Biomedical Engineering, 2012., 2012.)
    With technologıcal developments in X-ray imaging, digital systems started to replace analog systems. Principle advantages of digital X-ray imaging are; it has lower cost (in the long run), is ready to be processed with a ...
  • Image reconstruction in dental tomosynthesis with stationary detector 
    Sur, Yunus Burak. (Thesis (M.S.)-Bogazici University. Institute of Biomedical Engineering, 2019., 2019.)
    Tomosynthesis is an imaging modality for analyzing anatomical structures. X-ray images from different angles are used for reconstruction in tomosynthesis. In contrast to computed tomography, X-ray tube moves around a ...
  • Possible evolutions of isolated neutron stars 
    Şahin, Serkan. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2006., 2006.)
    Neutron stars are end products of stellar evolution, like black holes and white dwarfs. Since they radiate in all bands of the electromagnetic spectrum and as their densities and magnetic fields are much higher than normal ...
