Over the last years there has been a strong trend of publishing health data in anonymized format in order to make it available for research. This is also true for medical imaging where the DICOM standard is the predominant data format and network protocol. This paper proposes an extension to any DICOM networking infrastructure that permits sharing of medical images in an anonymized way. Standard DICOM software is utilized on client and server side. While offering researchers access to all images in anonymous format, the architecture enables authorized clinicians to access the same images including their original patient information (name, institution, etc.). Identifying parts and anonymous parts of the image data are stored to geologically different databases. Together with sophisticated network protocols, patient privacy is fully preserved.
在过去几年中，为了便于研究使用，以匿名形式发布健康数据已成为一种强劲趋势。医学成像领域也是如此，其中DICOM标准是主要的数据格式和网络协议。本文提出了对任何DICOM网络基础设施的扩展，允许以匿名方式共享医学图像。客户端和服务器端均使用标准的DICOM软件。该架构在为研究人员提供匿名格式的所有图像访问权限的同时，也使授权临床医生能够访问相同的图像，包括其原始患者信息（姓名、机构等）。图像数据的标识部分和匿名部分存储在地理位置不同的数据库中。再结合先进的网络协议，患者隐私得到了充分保护。
