Figure 5.
(a) – (d): Snapshots of the CUSE shear wave propagation movie at different time instants obtained from the 9L-D probe on the LE9. A 4-tooth focused comb-push was transmitted and the resulting shear waves were tracked by TAST. The numbers in (a) indicate the push beam location. (e): schematic plot of the comb-push beams and the imaging zones (given a desired PRFe of 4 kHz and 128 imaging lines).
