with the state-of-the-art approaches. The tracking accuracy and robustness show that our algorithm has potential in 3D US-guided abdominal interventional therapies. Furthermore, more researches are needed to improve the computing speed of the algorithm to achieve real-time tracking.There does not appear to be any studies in the published literature on the stability of SARS-CoV-2 in climbing chalk powder (magnesium carbonate and/or calcium carbonate), which has been hypothesized to pose a potential risk of fomite transmission of coron
