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
