Abstract

The use of multi-dimensional wave extraction algorithm for a multi-receivers axial transmission ultrasound device used in bone evaluation is proposed. As far as we know, multi-dimensional signal processing techniques have never been implemented in this configuration. A SVD-based wavefront extraction is implemented for the characterization of an energetic low frequency contribution. Velocity accuracy is estimated on a synthetic dataset. Furthermore, the energetic low frequency removal is illustrated on in vivo signals. Results are promising as for the application of multi-dimensional techniques in medical ultrasound used in transmission
