Abstract

In this paper, we have proposed an improved tensor-analysis based method with adaptive beam sequence and RF processing to enhance the needle visualization. In vivo study has proved that the needle CNR has been improved for more than 4 times on 30 femoral and deep interscalene blocks without introducing significant artifacts. We believe the proposed method could be useful in the real-time guidance of needle insertion.
