    • Acoustical tuning of CMUT receiver arrays 

      Taşdelen, Akif Sinan; Atalar, Abdullah; Enhoş, Kerem; Köymen, Hayrettin (IEEE, 2016)
      Cell placement in an element and structural modifications on the array baffle significantly change the bandwidth, band shape and signal to noise ratio of a CMUT receiver array. In this paper, optimum receiver performance ...
    • Dr. Lütfi Doğan'ın biyografisi 

      Ersoy, Esin; Enhoş, Kerem; Hacialioğlu, Alican; Tandoğan, Yavuz Selim; Şimşek, İrem (Bilkent University, 2014)
    • Electrically unbiased and half frequency driven waterborne 16×16-element 2-D phased array CMUT 

      Enhoş, Kerem (Bilkent University, 2019-08)
      Capacitive micromachined ultrasonic transducers (CMUT) are typically used as arrays consisting of separate cells or interconnected sub arrays, and these cells have several operation modes. Design procedure and ...
    • Pulse coding with complementary Golay sequences for signal to noise ratio improvement in ultrasound mammography 

      Kumru, Yasin; Enhoş, Kerem; Köymen, Hayrettin (Acoustical Society of America, 2018-11)
      The main objective of this study is to obtain improved detection of 50 μm breast microcalcifications in ultrasound mammography. A synthetic transmit aperture imaging method combined with coded excitation and pulse compression ...
    • Transmitting CMUT arrays without a DC bias 

      Enhoş, Kerem; Taşdelen, Akif Sinan; Yılmaz, Mehmet; Atalar, Abdullah; Köymen, Hayrettin (IEEE Computer Society, 2019)
      This study focuses on design, simulation, fabrication and measurement of transmitting CMUT arrays with unbiased mode of operation. We presented a design procedure considering the radiation pattern, Rayleigh distance and ...
