The need for long-term storage requires the future migration of image data from a PACS to its successor system. This paper considers the cost of such migration It is proposed that storage of data as "documents" in DICOM Part 10 formats on industry-standard media could reduce the time and cost of data migration relative to on-line DICOM transfer. The relation to present efforts in developing document-oriented electronic patient records is discussed. DICOM Part 10 files are found to be a sufficient representation of image documents, but additional software tools will be needed to reach its full potential. There is a significant cost benefit of the document storage method, but it is one of many factors which must be balanced in the selection of a PACS.
长期存储的需求要求未来将影像数据从 Picture Archiving and Communication System（PACS）迁移到其后续系统。本文探讨了这种迁移的成本。建议将数据以 DICOM 第 10 部分格式作为“文档”存储在行业标准介质上，相对于在线 DICOM 传输，这可以减少数据迁移的时间和成本。文中还讨论了与当前开发面向文档电子病历工作的关系。发现 DICOM 第 10 部分文件足以表示影像文档，但要充分发挥其潜力还需要额外的软件工具。文档存储方法具有显著的成本效益，但它只是 PACS 选择中必须权衡的众多因素之一。
