Coherent plane wave compounding allows to enhance the spatial resolution by maintaining high frame rates. Furthermore, by means of a phased array probe with adaptive beamforming, the imaging plane can be extended to the sides of the probe, although u

A tornado-like liquid metal vortex is driven by magnetic body forces. A continuously applied rotating magnetic field provides source of the angular momentum. A pulse of a much stronger travelling magnetic field drives a converging flow that temporari
