An endoscopie imaging system based on a two-dimensional CMUT array: real-time imaging results
Wygant, Ira O.; Zhuang, Xuefeng; Yeh, David T.; Vaithilingam, Srikant; Nikoozadeh, Amin; Oralkan, Ömer; Ergün, Arif Sanlı; Karaman, Mustafa; Khuri-Yakub, Butrus Thomas (IEEE, 2005)Real-time catheter-based ultrasound imaging tools are needed for diagnosis and image-guided procedures. The continued development of these tools is partially limited by the difficulty of fabricating two-dimensional array ... -
An integrated circuit with transmit beamforming and parallel receive channels for real-time three-dimensional ultrasound imaging
Wygant, Ira O.; Lee, Hyunjoo J.; Nikoozadeh, Amin; Yeh, David T.; Oralkan, Ömer; Karaman, Mustafa; Khuri-Yakub, Butrus Thomas (IEEE, 2006)We present the design of an integrated circuit (IC) that will be flip-chip bonded to a 16 x 16-element CMUT array. The IC provides 16 receive channels which can be configured to receive along either of the array diagonals ... -
Integrated ultrasonic imaging systems based on CMUT arrays: Recent progress
Wygant, Ira O.; Zhuang, Xuefeng; Yeh, David T.; Nikoozadeh, Amin; Oralkan, Ömer; Ergün, Arif Sanlı; Karaman, Mustafa; Khuri-Yakub, Butrus Thomas (IEEE, 2004)This paper describes the development of an ultrasonic imaging system based on a two-dimensional capacitive micromachined ultrasonic transducer (CMUT) array. The transducer array and front-end electronics are designed to ... -
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 ... -
A miniature real-time volumetric ultrasound imaging system
Wygant, Ira O.; Yeh, David T.; Zhuang, Xuefeng; Nikoozadeh, Amin; Oralkan, Ömer; Ergün, Arif Sanlı; Karaman, Mustafa; Khuri-Yakub, Butrus Thomas (SPIE-Int Soc Optical Engineering, 2005)Progress made in the development of a miniature real-time volumetric ultrasound imaging system is presented. This system is targeted for use in a 5-mm endoscopic channel and will provide real-time, 30-mm deep, volumetric ...
