What is a Routing Gateway?
A Routing Gateway locates routable images, determines where the images are to be routed to, and sends copies of those images to other locations. Routing is a function of the DICOM Gateway software. When properly configured, any DICOM Gateway can function as a Routing Gateway.
Typically, a Routing Gateway runs on a dedicated computer. At sites where only a small volume of images are produced, a Routing Gateway can coexist on the same computer as an Image Gateway or a Text Gateway.
Routing Prerequisites
For a site to be authorized to use a routing system:
An executed Site Agreement must be filed with the VistA Imaging HSD&D group.
Note: An updated site agreement must be filed if the routing system is altered (for
example: if site information changes, if a new destination is added, or if routing volume increases by 50% or more).
A contingency plan must be implemented at all sites in the routing system and filed with the VistA Imaging HSD&D group. The contingency plan must contain procedures to be followed should the routing system be unavailable.
General hardware and operational requirements for routing are summarized below. For detailed information, contact your VistA Imaging Implementation Manager.
Infrastructure Requirements
Routing relies on the following infrastructure:
If remote interpretation is being performed, one or more VistARad diagnostic workstations for the display of routed exams.
An operational VistA Hospital Information System, an operational Image Gateway, and an operational Routing Gateway, configured as described in this document.
An operational Local Area Network (LAN).
An operational Wide Area Network (WAN) with sufficient bandwidth to manage the anticipated volume of routed exams.
