摘 要:将代价敏感方法引入肺癌细胞图像识别,建立基于代价敏感图像层的肺癌细胞病理诊断系统(Cost-sensitive Image-level Lung Cancer Diagnosis System,CILCDS),并研究其临床应用价值。与既往方法比较,CILCDS在癌与正常细胞的判断以及癌细胞的分类识别诊断过程中取得了最低的错误分类代价0.37%以及更高的组织病理结果符合率97.61%。基于代价敏感图像层技术能够有效减少肺癌细胞病理诊断过程中的假阳性结果,有可能为肺癌细胞病理诊断提供一个更为有效的检测手段。 |

Abstract:Cost-sensitive methods introduced into cytopathological diagnosis,A Cost-sensitive Image-level Lung Cancer Diagnosis System(CILCDS) is proposed,and its clinical value is evaluated. CILCDS obtained lower misdiagnosis costs 0.37% and comparable precision 97.61% in normal/cancerous identification compared with other techniques. It suggests that CILCDS may reduce the false positive results in cytopathological detection of lung cancer and may provide a more effective means for cytopathological diagnosis of lung cancer. |
