Abstract

We present a robust methodology to quantify displacements in musculoskeletal ultrasound sequences. This paper extends the principles of 2D interframe displacements produced by our earlier work using hierarchical variable block size matching, to quantify displacement \emph{trajectories}. We provide novel solutions for probe motion, quantification of objects moving in the 3D volume traversing the 2D plane, and improving the temporal coherence of displacements for typical captured sequences, direct from modern ultrasound machines.
