Abstract

Real-time elastography is a promising dynamic tool providing viscoelastic properties of living tissue in vivo by advanced evaluation of the spatio-temporal vector motion in tissue. This study experimentally verified the performance of our proposed measurement system for practical evaluation of two-dimensional motion vector dynamics followed by pulsed shear wave generation and its propagation across a phantom.
