Enhance business continuity • High availability and disaster recovery
Reduce storage costs • Intelligent management of storage
costs in a clinically relevant matter
Reduce migration costs • Reducing the cost of data migration
when switching the software product
Enable image sharing • DICOM image distribution
Enable non-image sharing • Enterprise-wide integration of non-
image data and non-DICOM image data

Level 2 (DICOM) Imaging consolidation across enterprise
Level 3 (+XDS) Enterprise-wide clinical data consolidation
Level 4 (+XDS) Cross-enterprise patient repository & sharing
Level 1 (DICOM) Independence of PACS application
Scalable and Standards Compliant
Prepare for the next level
VNA design principle: neutrality
Application Neutrality (DICOM, HL7, IHE) • Leverage healthcare interoperability standards • Obtain information from departmental systems
through standards based interfaces: DICOM, HL7, IHE XDS
• Access information from the VNA through standards based interfaces: DICOM, IHE XDS, WADO
IT Platform Neutrality (Storage, Virtualization) • Leverage the continuous improvement in
infrastructure technology to lower cost • Leverage standards-based storage interfaces • Preserve your existing investment
Format Neutrality (DICOM Part 10, CDA) • Store information in native standardized format • Reduce migration costs

Patient centric model Central index, accessible
anywhere
A patient centric approach for data consolidation and sharing
Information Sharing • Single interface to the EMR • Single, multi-ology viewer • ZFP: no download, browser agnostic,
no admin rights
Infrastructure Sharing • Centralized information archive
• Information life cycle management
• Data security & access safeguards
• Scalable for future needs
• Disaster Recovery

Fast access to relevant information
For Clinicians: Integrated IHE XDS/XDS-I Consumer optimized for large data sets
• Provides patient centric view
• Uses XDS metadata for navigation and filtering
• Displays DICOM and non-DICOM information side-by-side
Other requirements
• Zero footprint – Web based without client-side
installs – Browser and OS agnostic
• EMR integration

Neutrality: standards-based access
For clinicians and specialists: Vendor neutral access
Multiple XDS / XDS-I Consumers can be used in parallel to access the patient centric record in the Enterprise XDS based VNA
Clinicians
• Integrated XDS / XDS-I Consumer with zero-footprint client provided as part of the VNA
Specialists
• XDS / XDS-I Consumer embedded in existing specialty applications, e.g. in RIS/PACS
