Abstract: A method for distinguishing between pulmonary arteries and pulmonary veins and a method for quantifying blood vessels are disclosed. The method for distinguishing between pulmonary arteries and pulmonary veins includes: forming a set of pulmonary vessels for points corresponding to pulmonary vessels, wherein each of the points of the set of pulmonary vessels has weight information; forming a tree from the points of the set of pulmonary vessels by using the weight information; and distinguishing between the pulmonary arteries and the pulmonary veins by separating the tree into a plurality of regions. The method for quantifying blood vessels includes: extracting blood vessels as a three-dimensional set of voxels based on medical images of an organ; finding the voxels of blood vessels included in a region of interest of the organ; and quantifying length information of the blood vessels by using the found voxels.
Abstract translation: 公开了一种用于区分肺动脉和肺静脉的方法以及用于定量血管的方法。 用于区分肺动脉和肺静脉的方法包括：形成一组对应于肺血管的点的肺血管，其中该组肺动脉血管的每个点具有体重信息; 通过使用权重信息从该组肺血管的点形成树; 并通过将树分离成多个区域来区分肺动脉和肺静脉。 量化血管的方法包括：基于器官的医学图像将血管提取为三维体素组; 找到包含在器官感兴趣区域的血管的体素; 以及通过使用发现的体素来量化血管的长度信息。

Abstract: The present disclosure relates to a method for generating an insertion trajectory of a surgical needle from an entry point to a target, including the steps of: preparing a medical image including the target and an anatomical structure; and extracting an insertion trajectory in consideration of at least one of a degree of invasion into the anatomical structure through the insertion trajectory and a distance of the insertion trajectory. Further, the present disclosure relates to a method for generating an insertion trajectory of a medical device, and a robot for interventional procedures including needle insertion.
