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 ...
Volumetric imaging using fan-beam scanning with reduced redundancy 2D arrays
(IEEE, 2006)
Phased array processing with a fully populated 2D array produces the best image quality but requires excessive number of active parallel front-end channels. Here we explore four array designs with reduced redundancy in ...
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 ...
Circuit model for given reflectance data constructed with mixed lumped and distributed elements for high speed/high frequency communication systems
(IEEE, 2005)
In this paper, a reflectance-based "non linear interpolation method" is presented to model the measured or computed data, obtained from a "passive one-port physical device" using mixed lumped and distributed elements. Mixed ...
Forward-looking IVUS imaging using an annular-ring CMUT array
(IEEE, 2005)
A 64-element, 1.15mm diameter annular-ring CMUT array was characterized and used for forward-looking IVUS imaging tests. The array was manufactured using low temperature processes suitable for CMOS electronics integration ...
A parametric approach to construct two-variable positive real impedance functions for the real frequency design of mixed lumped-distributed matching networks
(IEEE, 2004)
In this paper, a parametric approach to construct two-variable positive real driving point impedance functions characterizing lossless ladder networks with mixed lumped and distributed elements is presented. The proposed ...
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 ...
