Increasing radiology studies has led to the emergence of new requirements for management medical information, mainly affecting the storage of digital images. Today, it is a necessary interaction between workflow management and legal rules that govern it, to allow an efficient control of medical technology and associated costs. Another important topic that is growing in importance within the healthcare sector is compliance, which includes the retention of studies, information security, and patient privacy. Previously, we conducted a series of extensive analysis and measurements of pre-existing operating conditions. These studies and projects have been described in other papers. The first phase: hardware and software installation and initial tests were completed in March 2006. The storage phase was built step by step until the PACS-INR was totally completed. Two important aspects were considered in the integration of components: (1) the reliability and performance of the system to transfer and display DICOM images, and (2) the availability of data backups for disaster recovery and downtime scenarios. This paper describes the high-availability model for a large-scale PACS to support the storage and retrieve of data using CAS and DAS technologies to provide an open storage platform. This solution offers a simple framework that integrates and automates the information at low cost and minimum risk. Likewise, the model allows an optimized use of the information infrastructure in the clinical environment. The tests of the model include massive data migration, openness, scalability, and standard compatibility to avoid locking data into a proprietary technology.
放射学研究的增加导致了对管理医疗信息的新要求的出现，主要影响数字图像的存储。如今，工作流程管理及其所遵循的法律规则之间的有效互动是必要的，以允许对医疗技术和相关成本进行有效的控制。在医疗保健领域，另一个日益重要的重要主题是合规性，其中包括研究的保留、信息安全和患者隐私。
此前，我们对现有的操作条件进行了一系列广泛的分析和测量。这些研究和项目已在其他论文中进行了描述。
硬件和软件的安装和初步测试于 2006 年 3 月完成。存储阶段逐步构建，直到 PACS-INR 完全完成。在组件集成方面考虑了两个重要方面：（1）用于传输和显示 DICOM 图像的系统的可靠性和性能，以及（2）用于灾难恢复和停机场景的数据备份的可用性。
本文描述了一种用于大型 PACS 的高可用性模型，该模型使用 CAS 和 DAS 技术来支持数据的存储和检索，以提供一个开放的存储平台。该解决方案提供了一个简单的框架，可在低风险和最小风险的情况下以低成本集成和自动化信息。同样，该模型允许在临床环境中优化信息基础架构的使用。该模型的测试包括大规模数据迁移、开放性、可扩展性和标准兼容性，以避免将数据锁定在专有技术中。
