A cost-effective method for ultrasound volumetric imaging
(1996)
A synthetic receive aperture technique is explored for cost-effective ultrasound scanners with high frame rates and beam density. The technique provides ultrasound volumetric imaging where beam count is very large with 2-D ...
Segmentation of ultrasonic images using fuzzy sets
(1996)
An image segmentation technique based on fuzzy sets for ultrasonic B-scans is presented. The fuzzy c-means algorithm is adapted to B-scan images. The classes constituting a region are obtained through fuzzy partitioning ...
Herbicide penetration through isolated periderm and cuticular membranes
(1996)
The penetration of three herbicides through isolated potato periderm (PM) and pear fruit cuticular membranes (PFCM) as their commercial formulations was examined in two separate experimental methods involving infinite and ...
Motion estimation using common spatial frequencies in synthetic aperture imaging
(I E E E, 1996)
Correlation processing using fully common spatial frequencies of overlapping subapertures is explored for motion estimation between consecutive excitations in multi-element synthetic aperure imaging. Signals derived from ...
Beam space processing for low-cost scanners
(I E E E, 1996)
A subaperture processing technique suitable for low-cost ultrasound imaging systems is presented. The technique is based on multi-element synthetic aperture approach and beam interpolation. A large receive aperture is ...
An assessment of the effects of in-plane vibrations on the energy flow between coupled plates
(Academic Press Ltd, 1996)
The majority of the studies of energy transmission in plate-type structures are based on the assumption that the main component of the energy transfer is due to flexural waves, and the contribution of in-plane waves may ...
