The Added Value of Cascaded Plane Wave Imaging for Autocorrelation- and Cross-Correlation-Based Velocity Vector Imaging

Simulated and experimentally measured data from https://doi.org/10.1109/ojuffc.2025.3639374 are included. The article evaluates the velocity vector imaging performance of cascaded dual‑polarity wave (CDW) imaging compared to conventional plane‑wave imaging under varying signal‑to‑noise ratio conditions, using a basic autocorrelation and cross‑correlation based velocity estimator.

The dataset comprises simulated single‑scatterer motion, simulated and experimentally measured parabolic tube flow, and simulated rotating‑disk data. CDW imaging was performed using four pulses in a train.
