摘 要:由于肺部结节的形状多样,特征复杂,在人工进行处理的过程中会存在诸多问题,例如提取肺结节的过程困难和结节分割的精确度不高以及消耗大量人力财力等。文章采用了一种深度学习的模型——V-Net 模型,对肺结节进行分割,接着使用大型公开肺结节数据集 LUNA16 进行了实验,通过分割结果可以直观看到,该文所用深度学习方法在对辅助医师进行肺结节诊断治疗有一定的参考价值。

Abstract: Due to the diverse shapes and complex characteristics of pulmonary nodules, there are many problems in the process of manual processing, such as the difficult process of extracting pulmonary nodules, the low accuracy of nodule segmentation, the consumption of a lot of human and financial resources and so on. In this paper, a deep learning model, the V-Net model, is used to segment lung nodules, and then the large-scale public lung nodule data set LUNA16 is used for experiments. The segmentation results can be intuitively seen. The deep learning method used in this paper has a certain reference value in assisting physicians in the diagnosis and treatment of pulmonary nodules.
