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...
In this paper, we have proposed a tensor-based filtering method to enhance the SNR of hyperechoic spots in human breast ultrasound images while suppressing the speckle noise. The breast images were acquired by an Automatic Breast Ultrasound Scanner (ABUS), which offers high spatial resolution and the fast full breast exam capability. The enhanced images were then gone through a pattern recognition...
