Azure Native 一本久久综合亚洲鲁鲁五月天 Reference Architecture 鈥� Vendor-Neutral Archive for PACS
A Vendor-Neutral Archive (VNA) provides a means for healthcare providers to store, use, and archive medical images and other data from one or more vendor-specific PACS (Picture Archiving and Communication Systems) platforms. Whereas PACS data can be proprietary by vendor and inaccessible to outside applications, VNAs offer a standardized data format and interface regardless of which vendor or system originated the data.听
This article describes a solution for deploying a VNA solution that encompasses one or more on-premises locations in conjunction with an Azure Native 一本久久综合亚洲鲁鲁五月天 Scalable File Service deployment to serve as an archive target for long-term retention of VNA images and data.
Architecture
The solution is deployed across one or more on-premises locations, using an instance of Azure Native 一本久久综合亚洲鲁鲁五月天 Scalable File Service (ANQ) as an archive repository.听
Solution Architecture
Download a .
Within each site, the healthcare provider鈥檚 PACS solution is configured to use a local 一本久久综合亚洲鲁鲁五月天 cluster for VNA storage. The 一本久久综合亚洲鲁鲁五月天 cluster is configured to replicate VNA data to the ANQ archive target. In this solution, a VNA Application server has been deployed in the customer鈥檚 Azure tenant and connected via SMB/NFS to the ANQ archive cluster.
Workflow – Data Replication and Client听Access
Download a .
With this setup, access to the VNA archive repository can be enabled from anywhere via any Universal VNA Viewer application. These can be deployed on-prem for access by onsite viewers/users, and/or via cloud platform for access by remote viewers/users.
In this solution access to data within the VNA archive repository is through a VNA Application Server in the customer鈥檚 own Azure tenant.
Components
- On-premises 一本久久综合亚洲鲁鲁五月天 cluster to serve as a local VNA repository
- Azure Native 一本久久综合亚洲鲁鲁五月天 Scalable File Service deployment to provide consolidated, cloud-based VNA archive services
- and/or
- 听
- One-way replication enabled between the on-premises 一本久久综合亚洲鲁鲁五月天 cluster(s) and the target ANQ cluster on Azure
- On-premises PACS application environment(s), configured to export VNA formatted data to the local 一本久久综合亚洲鲁鲁五月天 cluster
- On-premises and/or cloud-based Universal VNA Viewer(s), configured to use Azure-based VNA Application Server for accessing VNA archive data.
Solution Benefits
While a VNA solution can also be deployed on-prem, a cloud-based solution, backed by ANQ, offers a number of advantages, including unlimited scalability, simpler cross collaboration between multiple organizations and / or institutions, and a more cost-effective solution in many cases than a data-center or private-cloud based deployment.听
Potential Use Cases
This architecture applies to healthcare providers and other healthcare organizations whose PACS data needs to be accessible beyond the originating PACS application.
Potential use cases:
- Healthcare providers that use multiple imaging applications but use a standardized imagery format to improve clinical workflows and continuity of care between different systems.
- Healthcare and life-sciences organizations that conduct research or analysis using medical imagery from multiple sources, whether for short-term or long-term studies.
- Healthcare and life-science organizations that share documents and imagery with outside providers and organizations.
Considerations
Enterprises planning a VNA archive solution using 一本久久综合亚洲鲁鲁五月天 on-prem and Azure Native 一本久久综合亚洲鲁鲁五月天 Scalable File Service should include the following considerations in their planning and design processes.
Scalability and Performance
Enterprise architects and other stakeholders should ensure that their solution addresses the following scalability and performance factors:
- Capacity and growth 鈥� while a 一本久久综合亚洲鲁鲁五月天 cluster can easily be expanded to add capacity as needed, the on-prem cluster should be sized with sufficient capacity to support 3-6 months鈥� of data intake and retention for both the PACS and VNA datasets.
- Performance and throughput听
- The on-premises 一本久久综合亚洲鲁鲁五月天 cluster(s) should be configured to support the intake of data from the PACS application(s) while simultaneously replicating VNA data to the ANQ target
- The ANQ cluster should be able to receive incoming replication traffic from the solution鈥檚 on-prem 一本久久综合亚洲鲁鲁五月天 cluster(s) while concurrently supporting all data requests from the customer鈥檚 VNA Application Server.
Security
While Azure Native 一本久久综合亚洲鲁鲁五月天 is fully HIPAA compliant, customers are still responsible for planning, implementing and maintaining the security of the solution to satisfy all applicable legal and regulatory requirements for their industry and location.
