长期监测发现近年来我国肺癌发病率上升至原先的4倍，气象等专家经过研究发现，灰霾是致肺癌高发的一个根本原因，特别是在城市。肺癌的早期诊断十分重要。利用计算机图像处理技术检测肺癌早期标志物--肺结节，可以提高肺癌诊断的准确率。据此设计了一个CAD系统，尝试通过四个步骤实现肺结节的检测：肺实质分割、感兴趣区（ROI）的提取、特征的提取与计算、肺结节检测。

Through long-term monitoring, the incidence of lung cancer has increased to four times higher than the past. The weather experts conclude that the grey haze is the prime cause of high incidence of lung cancer, especially in cities. It is important to early diagnose lung cancer. This project will use the computer image processing technology to detect early lung cancer markers, lung nodules, to improve the accuracy in diagnosis of lung cancer, at the same time can reduce the workload of doctors. A CAD system is designed. The detection of lung nodules are realized by four steps: lung parenchyma segmentation, interested area (ROI) extraction, feature extracting and calculating, lung nodule detection.
