Adaptive Spatial Compounding for Needle Visualization

In this paper, we have proposed an adaptive tensor-analysis based spatial compounding method to enhance the needle visualization. In-vitro study has proved that the needle CNR has been improved from 0.78 to 4.58 without introducing significant artifacts. Meanwhile, no manual adjustments are needed during the procedure since the proposed method can enhance the needle with a big range of insertion angles under the same configuration. We believe the proposed method could be useful in the real-time guidance of needle insertion.
