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 ...
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 ...
