论文摘要
胸部计算机断层扫描的气道分割在肺部疾病诊断中起着至关重要的作用。与手动分割相比，基于U-NET体系结构的计算机辅助气道分割更有效，更准确。在本文中，我们采用了由骰子损失功能培训的U $^2 $ -NET，以基于ATM'22提供的299次培训CT扫描来对气道树进行建模。从训练中将派生的显着性概率图应用于验证数据以提取相应的气道树。该观察结果表明，大多数分割的气道树从准确性和连通性的角度表现出色。将诸如非航空区域标签和去除之类的改进应用于某些获得的气道树模型，以显示二进制结果的最大组成部分。
Airway segmentation from chest computed tomography scans has played an essential role in the pulmonary disease diagnosis. The computer-assisted airway segmentation based on the U-net architecture is more efficient and accurate compared to the manual segmentation. In this paper we employ the U$^2$-net trained by the Dice loss function to model the airway tree from the multi-site CT scans based on 299 training CT scans provided by the ATM'22. The derived saliency probability map from the training is applied to the validation data to extract the corresponding airway trees. The observation shows that the majority of the segmented airway trees behave well from the perspective of accuracy and connectivity. Refinements such as non-airway regions labeling and removing are applied to certain obtained airway tree models to display the largest component of the binary results.
