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 ... -
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 ... -
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 ...
