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 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 ...
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 ...
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 ...
Co-array optimization of CMUT arrays for forward-looking IVUS
(IEEE, 2009-09)
The ring annular array structure is a preferred configuration for implementing Forward-Looking IVUS (FLIVUS) catheters as it allows for volumetric imaging as well as use of a guidewire at the center. CMUT technology is ...
