Annular CMUT arrays for side looking intravascular ultrasound imaging
(IEEE, 2007)
Although side looking intravascular ultrasound (SL-IVUS) imaging systems using single element piezoelectric transducers set the resolution standard in the assessment of the extent of coronary artery disease, improvements ...
Forward-looking IVUS imaging using a dual-annular ring CMUT array: Experimental results
(IEEE, 2007)
This paper presents the experimental results on forward-looking Intravascular ultrasound (FL-IVUS) using dual-annular-ring CMUT arrays. The array has a diameter of 1mm including bondpads which consists of separate, concentric ...
Dual-annular-ring CMUT array for forward-looking IVUS imaging
(IEEE, 2006)
We investigate a dual-annular-ring CMUT array configuration for forward-looking intravascular ultrasound (FL-IVUS) imaging. The array consists of separate, concentric transmit and receive ring arrays built on the same ...
Beamforming and hardware design for a multichannel front-end integrated circuit for real-time 3D catheter-based ultrasonic imaging
(SPIE-Int Soc Optical Engineering, 2006)
We are working on integrating front-end electronics with the ultrasound transducer array for real-time 3D ultrasound imaging systems. We achieve this integration by flip-chip bonding a two-dimensional transducer array to ...
Experimental study of dual-ring CMUT array optimization for forward-looking IVUS
(IEEE, 2011)
Forward-looking (FL) catheters have guiding and volumetric imaging capacities which are highly desirable for IVUS applications. Large channel and firing counts have to be reduced to enable 3-D real-time imaging and simplify ...
CMUT-based volumetric ultrasonic imaging array design for forward looking ICE and IVUS applications
(SPIE-Int Soc Optical Engineering, 2013)
Designing a mechanically flexible catheter based volumetric ultrasonic imaging device for intravascular and intracardiac imaging is challenging due to small transducer area and limited number of cables. With a few parallel ...
Evaluation of CMUT annular arrays for side-looking IVUS
(IEEE, 2009)
Side-looking (SL) IVUS probes are extensively used for management of cardiovascular diseases. Currently SL-IVUS imaging probes use either a single rotating transducer element or solid-state arrays. Probes with single ...
A miniature real-time volumetric ultrasound imaging system
(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 ...
Integrated ultrasonic imaging systems based on CMUT arrays: Recent progress
(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 ...
An endoscopie imaging system based on a two-dimensional CMUT array: real-time imaging results
(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 ...
