基于专家系统的肺肿瘤数据库的开发研究

Exploitation and research of lung tumor database based on expert system

目的:结合肺癌的病理学和影像学诊断技术,引入计算机辅助诊断的肺癌专家系统,应用医学信息技术,研究肺肿瘤数据库的设计和开发。方法:快速原型法;面向对象的程序设计。1)计算机技术采用微软Windows平台,Windows Internet In-formation Service服务提供基于Web,甲骨文Oracle10g数据库,微软ASP.net开发工具;2)医学诊断技术基于肺癌的病理学和影像学诊断理论和实践;3)计算机辅助诊断技术是基于图像识别和"知识"的肺结节检测专家系统。结果:系统由人机交互界面、肺结节知识库和推理机(肺癌检测专家系统)、标本库、综合数据库、数据获取5个子系统构成。其中,综合数据库是整个系统的核心。肺癌计算机辅助诊断专家系统的关键技术为基于国际HL7和DIC-COM标准的医疗信息学。结论:设计及实现基于肺癌计算机辅助诊断专家系统的肿瘤数据库,有望对肺癌的诊断提供更便捷和准确的手段,同时也为将来建设全民健康档案提供相关的标准化数据来源。

OBJECTIVE：Integrated with pathology and radiology diagnostic technique for lung cancer,to introduce lung tumor computer assisted diagnostic（CAD）expert system to the exploitation and research of the state-of-art design of lung tumor database with information technology.METHODS：Rapid prototyping and object-oriented programming technology.1）Computer technology apply Windows Platform and Internet Information Service provide application service based on Web,Oracle database,Microsoft ASP.net developing tools;2）Medical diagnostic apply pathology and radiology principle and operation;3）CAD apply lung nodes detecting system based on the expert system using visualization and ＂knowledge＂ technique.RESULTS：The system contained human-computer interaction system,lung nodule repository and inference engine（lung cancer detection system）,specimen database,synthesis database and data-fetching system.Synthesis database was the key of the whole system.The key technique of Lung CAD expert system was Medical informatics based on international HL7,DICCOM standard.CONCLUSION：Present the lung tumor database scheme based on lung CAD expert system and integrated digitalization specimen management,design and realize a leading technique lung tumor database system for more easy and exact diagnostic of lung tumor as well as provide standard data for future electric healthcare record.
