DICOM SR研究

Research on DICOM SR

主要对医学数字成像和通信(DICOM)标准结构化报告(SR)的信息模型进行了研究,简单介绍了DICOM目录(DIR)文件。DICOM DIR文件是基于医学信息的结构文件。根据DICOM标准中定义的DICOM DIR文件特性,可以通过DICOM DIR文件找出SR中所引用的复合对象,从而显示SR中涉及到的各种复合对象,这样就提出了通过DICOM DIR文件查找DICOM文件集的模型,有效提高SR引用复合对象的效率,提高了访问数据的能力,为科学研究及医疗数据的知识挖掘与应用提供了大量可利用的素材,利于对大量医疗信息进行分析?研究?分类?总结和提取。

This paper is aimed to research into the information model of the Digital Imaging and Communication in Medicine（DICOM） Structured Reporting（SR）,and to introduce DICOM information object definitions（IODs） and services used for the storage and transmission of SR.The DICOM services are concerned with storage,query,retrieval,and transfer of data.and give a brief introduction to DICOM DIR.DICOM DIR is a file based on medical information.According to the DICOM DIR definition in the DICOM part ten,it may be found that the composite objects referenced in the DICOM SR.So putting forward the management of DICOM files by DICOM DIR sets,It effectively improves the efficiency of the object referenced by SR.This can increase the ability to access the data.For scientific research,medical data mining and applications,DICOM SR can profit the communication of medical information in different hospitals,and this can be useful for the analysis,research,summary,classification and extraction of a large quantity of medical information.
