An annular CMUT array beamforming system for high-frequency side looking IVUS imaging
(2010)A CMUT annular array system for Side-Looking Intravascular Ultrasound (SL-IVUS) with fixed transmit and dynamic receive focusing capabilities has been developed. The system was experimentally characterized and validated ... -
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 ... -
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 ... -
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 ... -
An integrated circuit with transmit beamforming and parallel receive channels for 3D ultrasound imaging: testing and characterization
(IEEE, 2007)The cost and complexity of medical ultrasound imaging systems can be reduced by integrating the transducer array with an integrated circuit (IC). By incorporating some of the system's front-end electronics into an IC, bulky ... -
Phased subarray imaging for low-cost, wideband coherent array imaging
(IEEE, 2003)The front-end hardware complexity of conventional full phased array (FPA) imaging is proportional to the number of array elements. Phased subarray (PSA) imaging has been proposed as a method of reducing the hardware ... -
Subarray delta-sigma beamforming for ultrasonic imaging
(IEEE, 2002)We present a beamforming architecture based on subarray processing with non-uniform oversampling 1-bit delta-sigma (??) modulation. The subarray processing combines conventional phased array and synthetic aperture approaches ... -
A tunable analog delay element for high-frequency dynamic beamforming
(IEEE, 2009)Implementing beamforming for high frequency arrays is challenging because of the accurate delay requirements at high frequencies. High frequency digital beamforming is not suitable for catheter based applications as a large ...
