VPN Direct Connect

Overview

We provide a secure VPN-based connectivity option that allows healthcare institutions to establish a private network tunnel between their on-premises PACS system and our cloud services. This integration supports DICOM standard protocols C-STORE and STOW-RS to facilitate reliable image and metadata transmission.

Key Benefits

• Enhanced Security: Encrypted communication over a private VPN tunnel.
• Compliance: Meets HIPAA and industry security requirements.
• Performance: Low-latency data transfer for real-time workflows.
• Simplicity: Minimal changes to existing PACS infrastructure.

How It Works

1. VPN Tunnel Establishment
   • A site-to-site or client VPN is configured between the hospital network and our cloud environment.
   • IP routing ensures that PACS traffic is directed through the tunnel.
2. DICOM Protocol Support
   • C-STORE: Traditional DICOM push mechanism for sending studies from PACS to cloud.
   • STOW-RS: RESTful DICOM web service for modern HTTP-based transfers.
3. Integration Workflow
   • PACS pushes images via C-STORE or STOW-RS through the VPN tunnel.
   • Our cloud services automatically ingest, process, and store the incoming studies.
   • Acknowledgements and status updates are returned to the PACS system over the same secure channel.

Tips

• Identical studies with the same StudyInstanceID uploaded within a 5 minute period will be overwritten

Security and Compliance

• All VPN connections use industry-standard encryption (e.g., IPsec, TLS).
• Access controls and network segmentation enforce strict isolation.
• Audit logs track all DICOM transactions for compliance reporting.
