Abstract
Methods and systems for improving correlation of shear displacement waveforms are presented. The method includes delivering one or more reference pulses to a plurality of target regions to detect corresponding initial positions. Further, a plurality of pushing pulse segments are delivered to one or more pushing locations, where one or more parameters corresponding to the plurality of pushing pulse segments are adapted for generating a shear displacement waveform with a desired wave shape. Additionally, one or more tracking pulses may be delivered to the plurality of target regions for detecting displacements of at least a subset of the target regions as a function of time. Particularly, the displacements are determined as time samples of the shear displacement waveform. Subsequently, a shift between the shear displacement waveform detected at least two different target regions in the subset of the plurality of target regions is detected.
