    • Digital beamforming techniques and VLSI circuits for medical ultrasound imaging 

      Karaman, Mustafa (Bilkent University, 1992)
      For phased array medical ultrasound imaging, digital beamforming techniques and VLSI circuits are studied to form a fully digital receive front-end hardware. To increase the timing accuracy in beamforming, a computationally ...
    • A phase aberration correction method for ultrasound imaging 

      Karaman, M.; Atalar, Abdullah; Köymen, Hayrettin; O'Donnell, M. (IEEE, 1993)
      A computationally efficient method for phase aberration correction in ultrasound imaging is presented. The method is based on time delay estimation via minimization of the sum of absolute differences between radio frequency ...
    • Reduction of effects of inactive array elements in phase aberration correction 

      Karaman, Mustafa; Köymen, Hayrettin; Atalar, Abdullah; O'Donnell, M. (IEEE, 1993)
      Phase aberration correction based on time delay estimation via minimization of sum of absolute difference (SAD) between radio frequency (RF) signals of neighboring elements is studied in the presence of missing elements. ...
