Imaging Archive for Magnetic Resonance Imaging Systems

描述（由申请人提供）：A.A.马蒂诺斯生物医学成像中心（以前称为MGH-NMR中心）迫切需要一个用于存储和检索成像数据的档案系统。该中心的四(4)台活跃的人类研究MRI扫描仪和三(3)台动物系统被100多个不同的用户使用，每个用户都负责将自己的数据存档。这些用户大多没有放射科学方面的背景，因此不习惯数据存档的详细要求。正因为如此，尽管经过了广泛的培训和努力，数据丢失还是很常见，在一些调查人员中可能高达1%到3%。一个安全的、冗余的档案系统加上一个放射学信息系统（RIS）可以防止这种损失。除了这一需要外，一些目前资助的项目在科学上将受益于一个编目档案，该档案允许在适当的人类研究指导方针下进行回顾性分析。例如，一位使用功能磁共振成像（fMRI）进行大脑制图的神经科学家可能会学习一种新的分析技术，并希望使用新工具重新分析两年的数据。中央存档使得检索数据以检验这种假设的任务变得可行。此外，进行多中心临床研究所需的技术分析将通过这种档案/RIS组合得到促进。这些分析包括跨时间点的研究内部比较，以确保扫描仪的稳定性，测量扫描仪的技术参数，如一天中的时间对扫描仪噪声的影响，新软件或硬件升级对图像质量的影响。我们提出的RIS系统还可以在扫描时存储扫描后的同意表格和其他数据，以便进行中央存档和检索，所有这些都具有复杂的访问控制。这种工具在帮助调查人员保持完全符合HIPAA方面也非常有益，特别是当对此类隐私要求的解释随着时间的推移而修改时。例如，某些体积核磁共振扫描的质量足够高，可以识别受试者的面部，这可能违反了隐私规则。中央存档将为我们提供一个公共平台，使我们能够自动化所需的隐私工具/协议，从而使我们的中心能够为希望专注于科学而不是图像存储细节的用户社区提供完全符合hipaa的服务。总的来说，这种需要的资源将极大地促进许多美国国立卫生研究院资助的研究者和未来几年的调查。

DESCRIPTION (provided by applicant): The A.A. Martinos Center for Biomedical Imaging (formerly known as the MGH-NMR Center), has an acute and growing need for an archival system for storage and retrieval of imaging data. The Center's four (4) active human research MRI scanners and three (3) animal systems are used by over 100 different users, each of whom is responsible for archiving their own data. Most of these users have backgrounds that are not in the radiological sciences, and are therefore not accustomed to the detailed requirements for data archiving. Because of this, despite extensive training and efforts, data loss is all too common, perhaps 1% to as much as 3% among some investigators. A secure, redundant archiving system coupled with a radiology information system (RIS) could prevent such loss. In addition to this need, a number of currently funded projects would scientifically benefit from a cataloged archive that allows, under appropriate human studies guidelines, retrospective analyses. For example, a neuroscientist using fMRI to do brain mapping may learn of a new analysis technique and wish to re-analyze two year's worth of data using the new tool. A central archive makes the task of retrieving data to test such a hypothesis practical. Furthermore, technical analyses needed to undertake multicenter clinical studies would be facilitated by such an archive/RIS combination. Such analyses include intra-study comparison across time points to ensure scanner stability, measurements of technical scanner parameters such as the effect of time of day on scanner noise, effect of new software or hardware upgrades on image quality. The RIS system we propose could also store scanned-in consent forms and other data at the time of scanning for central archiving and retrieval, all with sophisticated access controls. Such a tool would also be highly beneficially in assisting investigators in maintaining full HIPAA compliance, especially as interpretations of such privacy requirements are modified over time. For example, certain volumetric MRI scans are of high enough quality that a subject's face is recognizable, a potential violation of privacy rules. A central archive would provide a common platform for us to automate needed privacy tools/protocols, thereby allowing our Center to offer fully HIPAA-compliant services to a user community that wishes to focus on science, not on the details of image storage. Overall, this needed resource will greatly facilitate many NIH-funded investigators and investigations for years to come.
