摘要：
Shear Wave Dispersion Vibrometry (SDUV) is performed such that, after a single instance of their push pulse (218), a plurality of tracking pulses (222) are issued to sample, more than once, each of a plurality of locations (120, 148) on an associated monochromatic shear wave (116) in sampling that at least one of scans the plural locations in separate passes and, with a pulse of the plural tracking pulses, samples multiple ones of the plural locations concurrently. In a supplementary aspect, phase difference, for a given moment, is determined by taking into account intersample delay (156), if the determination relies on samples that are taken at different times.
