Design of a front-end integrated circuit for 3D acoustic imaging using 2D CMUT arrays
(IEEE-INST Electrical Electronics Engineers Inc, 2005-12)
Integration of front-end electronics with 2D capacitive micromachined ultrasonic transducer (CMUT) arrays has been a challenging issue due to the small element size and large channel count. We present design and verification ...
Coherent array imaging using phased subarrays. Part II: Simulations and experimental results
(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 ...
Annular-ring CMUT arrays for forward-looking IVUS: Transducer characterization and imaging
(IEEE, 2006-02)
In this study, a 64-element, 1.15-mm diameter annular-ring capacitive micromachined ultrasonic transducer (CMUT) array was characterized and used for forward-looking intravascular ultrasound (IVUS) imaging tests. The array ...
Vapor-induced film formation from low-T-g particles for different solvent compositions
(Elsevier Inc, 2006-05-15)
The photon transmission method was used to study latex film formation from poly(vinyl acetate) (PVAc) particles induced by two different solvents. Films with the same latex content were prepared from PVAc particles and ...
Integration of 2D CMUT arrays with front-end electronics for volumetric ultrasound imaging
(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 ...
An integrated circuit with transmit beamforming flip-chip bonded to a 2-D CMUT array for 3-D ultrasound imaging
(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 ...
