摘要

提出了一种用于骨评估的多接收机轴向传输超声装置的多维波提取算法。据我们所知，多维信号处理技术从未在这种配置中实现过。基于奇异值分解(svd)的波前提取实现了高能低频贡献的表征。在一个合成数据集上估计速度精度。此外，对体内信号进行了高能低频去除。结果表明，多维技术在医用超声传输中的应用前景广阔

Development of a Multi-Dimensional SVD based Technique for Multi-Receivers Ultrasound used in Bone Status Characterization

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
