匹配两种人类气道树之间对应的分支点，以及为人类气道树的段和分支点分配解剖学名称，对临床应用和生理学研究具有重要意义。在过去，由于缺乏能够容忍假分支和体内树典型解剖变异的自动化算法，这些任务通常是手动执行的。在本文中，我们提出了在没有任何人为干预和在短计算时间内完成分支点匹配和体内树解剖标记的算法。不需要手工修剪假树枝。当与人类专家提供的参考数据进行验证时，自动化方法的结果显示出高度的准确性。计算机找到的可验证分支点匹配与专家结果一致的比例为92.9%。对于解剖标记，97.1%的自动分配的节段标签被发现是正确的。
Matching of corresponding branchpoints between two human airway trees, as well as assigning anatomical names to the segments and branchpoints of the human airway tree, are of significant interest for clinical applications and physiological studies. In the past, these tasks were often performed manually due to the lack of automated algorithms that can tolerate false branches and anatomical variability typical for in vivo trees. In this paper, we present algorithms that perform both matching of branchpoints and anatomical labeling of in vivo trees without any human intervention and within a short computing time. No hand-pruning of false branches is required. The results from the automated methods show a high degree of accuracy when validated against reference data provided by human experts. 92.9% of the verifiable branchpoint matches found by the computer agree with experts' results. For anatomical labeling, 97.1% of the automatically assigned segment labels were found to be correct.
