  • Coherent array imaging using phased subarmys. Part II: Simulations and experimental results 

    Johnson, Jeremy A.; Oralkan, Ömer; Ergün, Arif Şanlı; Demirci, Utkan; Karaman, Mustafa; Khuri-Yakub, Butrus T. (IEEE-INST Electrical electronics engineers inc, 2005-01)
    The basic principles and theory of phased subarray (PSA) imaging imaging provides the flexibility of reducing I he number of front-end hardware channels between that of classical synthetic aperture (CSA) imaging-which uses ...
  • Forward-viewing CMUT arrays for medical Imaging 

    Demirci, Utkan; Ergun, Arif Şanlı; Oralkan, Ömer; Karaman, Mustafa; Khuri-Yakub, Butrus T. (IEEE-INST Electrical Electronics Engineers Inc, 2004-08)
    This paper reports the design and testing of forward-viewing annular arrays fabricated using capacitive micromachined ultrasonic transducer (CMUT) technology. Recent research studies have shown that CMUTs have broad frequency ...
  • An Integrated Circuit With Transmit Beamforming Flip-Chip Bonded to a 2-D CMUT Array for 3-D Ultrasound Imaging 

    Wygant, Ira O.; Jamal, Nafis S.; Lee, Hyunjoo; Nikoozadeh, Amin; Oralkan, Ömer; Karaman, Mustafa; Khuri-Yakub, Butrus T. (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2009-01)
    State-of-the-art 3-D medical ultrasound imaging requires transmitting and receiving ultrasound using a 2-D array of ultrasound transducers with hundreds or thousands of elements. A tight combination of the transducer array ...
  • Integration of 2D CMUT arrays with front-end electronics for volumetric ultrasound imaging 

    Wygant, Ira O.; Zhuang, Xuefeng; Yeh, David T.; Oralkan, Ömer; Ergün, Arif Şanlı; Karaman, Mustafa; Khuri-Yakub, Butrus T. (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2008-02)
    For three-dimensional (3D) ultrasound imaging, connecting elements of a two-dimensional (2D) transducer array to the imaging system's front-end electronics is a challenge because of the large number of array elements and ...
  • Minimally Redundant 2-D Array Designs for 3-D Medical Ultrasound Imaging 

    Karaman, Mustafa; Wygant, Ira O.; Oralkan, Ömer; Khuri-Yakub, Butrus T. (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2009-07)
    In real-time ultrasonic 3-D imaging, in addition to difficulties in fabricating and interconnecting 2-D transducer arrays with hundreds of elements, there are also challenges in acquiring and processing data from a large ...
