Abstract:Aberration correction for ultrasonic b-scan images can be effectively implemented with less computation by employing cross correction, i.e., using a single set of aberration corrections computed for a reference aperture position to correct the transmit and receive focus at other points within an image region defined as the isoplanatic patch. An uncomplicated implementation of this approach compensates the signal at each location in the aperture with the aberration correction from the corresponding location in … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
