Lung cancer is one of the major types of cancer in the world. Survival rate can be increased if the disease can be identified early. Posterior and anterior chest radiography and computerized tomography scans are the most used diagnosis techniques for detecting tumor from lungs. Posterior and anterior chest radiography requires less radiation dose and is available in most of the diagnostic centers and it costs less compared to the remaining diagnosis techniques. So PA chest radiography became the most commonly used technique for lung cancer detection. Because of superimposed anatomical structures present in the image, sometimes radiologists cannot find abnormalities from the image. To help radiologists in diagnosing tumor from PA chest radiographic images range of CAD scheme has been developed for the past three decades. These computerized tools may be used by radiologists as a second opinion in detecting tumor. Literature survey on detecting tumors from chest graphs is presented in this paper.
肺癌是全球主要的癌症类型之一。如果能早期发现该疾病，生存率可以提高。胸部前后位X线摄影和计算机断层扫描是检测肺部肿瘤最常用的诊断技术。胸部前后位X线摄影所需辐射剂量较少，在大多数诊断中心都可进行，且与其他诊断技术相比成本较低。因此，胸部后前位X线摄影成为肺癌检测最常用的技术。由于图像中存在重叠的解剖结构，有时放射科医生无法从图像中发现异常。在过去三十年里，为帮助放射科医生从胸部后前位X线摄影图像中诊断肿瘤，已经开发了一系列计算机辅助检测（CAD）方案。这些计算机化工具可被放射科医生用作检测肿瘤的第二种意见。本文介绍了关于从胸部X线片检测肿瘤的文献综述。
