Routing Overview

Routing User Guide 

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. 

For a site to be authorized to use a routing system:  

ƒ  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). 

ƒ  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. 

Routing relies on the following infrastructure: 

ƒ  If remote interpretation is being performed, one or more VistARad diagnostic 

workstations for the display of routed exams. 

ƒ  An operational VistA Hospital Information System, an operational Image Gateway, 

and an operational Routing Gateway, configured as described in this document. 

ƒ  An operational Local Area Network (LAN). 

ƒ  An operational Wide Area Network (WAN) with sufficient bandwidth to manage the 

anticipated volume of routed exams. 

ƒ  Windows-based servers to provide exam storage at each routing destination, 

configured as described in this document.
