摘要
CT肺部图像结节的轮廓对于评价计算机辅助诊断算法具有重要意义。本文利用LIDC数据库中XML注释文档中给出的结节信息,通过Matlab编程,对于大结节(直径≥3mm)用红色显示其轮廓点,对于小结节(直径<3mm)用蓝色正方形显示其大致位置,从而实现了肺结节轮廓及位置的可视化标注。本课题的研究为今后更好地利用LIDC数据库资源提供了便利。
The outlines of lung nodules on CT images are of great significance for the evaluation of computer-aided diagnosis （CAD） algorithm. LIDC database. In this paper, the information on lung nodules in XML-formatted notation files of LIDC is used after Matlab programming. Large nodules （diameter greater than 3 mm） are displayed with red outline and small nodules （diameter less than 3 ram） with a blue square to show their locations in brief, and therefore the visual marks of the outline and location of lung nodules can be realized. The research on this subject will facilitate to make use of the resources of LIDC database better in the future.
