Abstract
Official abstract text for this publication.
A shear wave velocity solution is provided for medical ultrasound imaging. Rather than determining shear wave information for each location based on distance from the origin of the shear wave and time to peak displacement for the location, displacement profiles resulting from different combinations of origin and detection locations are correlated. Shear information is detected using displacements from a diverse spatial combination of transmission locations and detection locations. The correlation combination is used in a same function for simultaneously solving for the delays for multiple lateral locations. Spatial diversity and layered correlation may provide for more accurate shear wave estimation.
First claim
Opening claim text (preview).
I claim: 1. A system for solving for shear wave information in medical ultrasound imaging, the system comprising: a receive beamformer operable to output data representing spatial locations as a function of received acoustic signals; a processor configured to estimate tissue displacements due to a shear wave as a function of a level of similarity between sets of the output data, compute correlation coefficients of at least one pair of the processor estimated tissue displacements…
