可扩展神经影像学存档工具包（XNAT）是一个软件平台，旨在促进神经影像学及相关数据的常见管理和提高工作效率。特别是，XNAT能够实现质量控制流程，并提供对数据的安全访问和存储。XNAT遵循三层架构，包括数据存档、用户界面和中间件引擎。数据可以以XML格式或通过数据录入表单输入到存档中。新添加的数据在经过授权用户验证之前会存储在虚拟隔离区中。XNAT随后会维护一个历史记录文件，以跟踪对所管理数据的所有更改。用户通过一个安全的网络应用程序访问存档。该网络应用程序提供了许多质量控制和提高工作效率的功能，包括数据录入表单、特定数据类型的搜索、跨数据类型组合的搜索、详细报告以及实验数据的列表、上传/下载工具、对标准实验室工作流程的访问以及管理和安全工具。XNAT还包括一个在线图像查看器，它支持许多常见的神经影像学格式，包括DICOM和Analyze。该查看器可以扩展以支持其他格式并生成自定义显示。通过使用XNAT管理数据，实验室能够更好地维护其数据的长期完整性，探索不同数据类型之间新出现的关系，并与更广泛的神经影像学社区共享其数据。
The Extensible Neuroimaging Archive Toolkit (XNAT) is a software platform designed to facilitate common management and productivity tasks for neuroimaging and associated data. In particular, XNAT enables quality-control procedures and provides secure access to and storage of data. XNAT follows a three-tiered architecture that includes a data archive, user interface, and middleware engine. Data can be entered into the archive as XML or through data entry forms. Newly added data are stored in a virtual quarantine until an authorized user has validated it. XNAT subsequently maintains a history profile to track all changes made to the managed data. User access to the archive is provided by a secure web application. The web application provides a number of quality control and productivity features, including data entry forms, data-type-specific searches, searches that combine across data types, detailed reports, and listings of experimental data, upload/download tools, access to standard laboratory workflows, and administration and security tools. XNAT also includes an online image viewer that supports a number of common neuroimaging formats, including DICOM and Analyze. The viewer can be extended to support additional formats and to generate custom displays. By managing data with XNAT, laboratories are prepared to better maintain the long-term integrity of their data, to explore emergent relations across data types, and to share their data with the broader neuroimaging community.
