Journal ArticleDOI
An integrated circuit with transmit beamforming flip-chip bonded to a 2-D CMUT array for 3-D ultrasound imaging
Ira O. Wygant,N. Jamal,Hyunjoo Lee,Amin Nikoozadeh,Omer Oralkan,Mustafa Karaman,Butrus T. Khuri-Yakub +6 more
TL;DR: It is shown that the IC can produce steered and focused ultrasound beams, and a combined IC and transducer array can lead to a portable, high-performance, and inexpensive 3-D ultrasound imaging system.
Journal ArticleDOI
Integrated Circuits for Volumetric Ultrasound Imaging With 2-D CMUT Arrays
Anshuman Bhuyan,Jung Woo Choe,Byung Chul Lee,Ira O. Wygant,Amin Nikoozadeh,Omer Oralkan,Butrus T. Khuri-Yakub +6 more
TL;DR: A 3-D imaging system using capacitive micromachined ultrasonic transducer (CMUT) technology that addresses many of the challenges in building such a system and demonstrates two approaches in integrating the transducers and the front-end electronics.
Journal ArticleDOI
Simultaneous transrectal ultrasound and photoacoustic human prostate imaging
Sri Rajasekhar Kothapalli,Sri Rajasekhar Kothapalli,Sri Rajasekhar Kothapalli,Geoffrey A. Sonn,Jung Woo Choe,Amin Nikoozadeh,Anshuman Bhuyan,Kwan Kyu Park,Paul Cristman,Richard E. Fan,Azadeh Moini,Byung Chul Lee,Jonathan Wu,Thomas E. Carver,Dharati Trivedi,Lillian Shiiba,Idan Steinberg,David M. Huland,Morten Fischer Rasmussen,Joseph C. Liao,James D. Brooks,Pierre Khuri-Yakub,Sanjiv S. Gambhir +22 more
TL;DR: The development and bench-to-bedside translation of an integrated TRUS and photoacoustic (TRUSPA) device that allows for real-time anatomical, functional, and molecular imaging of the human prostate and could be easily adopted into clinical workflows.
Journal ArticleDOI
Radiation Force as a Physical Mechanism for Ultrasonic Neurostimulation of the Ex Vivo Retina.
Mike D. Menz,Patrick Peiyong Ye,Kamyar Firouzi,Amin Nikoozadeh,Kim Butts Pauly,Pierre Khuri-Yakub,Stephen A. Baccus +6 more
TL;DR: The physical mechanism by which ultrasound is converted into an effective energy form to cause neurostimulation in the retina is studied and it is found that ultrasound acts via radiation force leading to a mechanical displacement of tissue.
Proceedings ArticleDOI
Analytical calculation of collapse voltage of CMUT membrane [capacitive micromachined ultrasonic transducers]
TL;DR: In this article, the authors proposed a fast numerical algorithm for the calculation of collapse voltage, which uses the parallel plate method to approximate the force distribution over the membrane, and then applies an analytical solution for the plate equation, loaded by the approximated force distribution.
