Coherent array imaging using phased subarrays. Part II: Simulations and experimental results
Johnson, Jeremy A.; Oralkan, Ömer; Ergün, Arif Sanlı; Demirci, Utkan; Karaman, Mustafa; Khuri-Yakub, Butrus Thomas (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 ... -
Coherent-array imaging using phased subarrays. Part I: Basic principles
Johnson, Jeremy A.; Karaman, Mustafa; Khuri-Yakub, Butrus Thomas (IEEE-INST Electrical Electronics Engineers Inc, 2005-01)The front-end hardware complexity of a coherent array imaging system scales with the number of active array elements that are simultaneously used for transmission or reception of signals. Different imaging methods use ... -
Forward-viewing CMUT arrays for medical Imaging
Demirci, Utkan; Ergün, Arif Sanlı; Oralkan, Ömer; Karaman, Mustafa; Khuri-Yakub, Butrus Thomas (IEEE-INST Electrical Electronics Engineers Inc, 2004-07)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 J.; Nikoozadeh, Amin; Oralkan, Ömer; Karaman, Mustafa; Khuri-Yakub, Butrus Thomas (IEEE-INST Electrical Electronics Engineers Inc, 2009-10)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 Sanlı; Karaman, Mustafa; Khuri-Yakub, Butrus Thomas (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 Thomas (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 ... -
