In this study, we present a computer assisted automatic diagnostic system for lung cancer that detects nodule candidates at an early stage from helical CT images of the thorax. Our diagnostic system consists of analytic and diagnostic procedures. In the analysis procedure, first we extract the lung and the pulmonary blood vessel regions using the fuzzy clustering algorithm, then we analyze the features of these regions using image processing technique. In the diagnosis procedure, we define diagnostic rules utilizing the extracted features which support the determination of the candidate nodule locations. We show the effectiveness of our system by giving the result of its application to image data for maass screening.

在这项研究中，我们提出了一种计算机辅助肺癌自动诊断系统，该系统可以从胸部螺旋 CT 图像中早期检测候选结节。我们的诊断系统由分析和诊断程序组成。在分析过程中，首先使用模糊聚类算法提取肺部和肺血管区域，然后使用图像处理技术分析这些区域的特征。在诊断过程中，我们利用提取的特征定义诊断规则，这些特征支持确定候选结节位置。我们通过将其应用到图像数据进行质量筛选的结果来展示我们的系统的有效性。
