    • Phase-correcting denoising for diffusion magnetic resonance imaging 

      Kafalı, Sevgi Gökçe (Bilkent University, 2018-04)
      Diffusion magnetic resonance imaging (MRI) is a low signal-to-noise ratio (SNR) acquisition technique when compared to anatomical MRI. Multiple acquisitions have to be averaged to overcome this SNR problem. However, ...
    • Phase-correcting non-local means filtering for diffusion-weighted imaging of the spinal cord 

      Kafalı, Sevgi Gökçe; Çukur, Tolga; Sarıtaş, Emine Ülkü (John Wiley, 2018)
      Purpose: DWI suffers from low SNR when compared to anatomical MRI. To maintain reasonable SNR at relatively high spatial resolution, multiple acquisitions must be averaged. However, subject motion or involuntary physiological ...
    • Simultaneous phase-correction and denoising for diffusion-weighted MRI 

      Kafalı, Sevgi Gökçe; Çukur, Tolga; Sarıtaş, Emine Ülkü (IEEE, 2016)
      Diffusion-weighted imaging (DWI) suffers from low SNR when compared to regular MRI images. To attain reasonable SNR levels with high spatial resolution, multiple acquisitions of each slice have to be acquired. These ...
