Routing User Guide Routing Overview
How On-Demand Routing Works
On-demand routing uses the same infrastructure as autorouting. However, in on-demand
routing, exams to be routed are manually selected by a VistARad user, rather than being
identified automatically by a Routing Gateway. With the proper security keys,
on-demand routing is available to any VistARad user in the routing system.
The following figure illustrates the transfer of images between a local and remote
VistARad workstation using on-demand routing.
1 On-demand routing can also be used to
transfer images to a DICOM destination such as a film printer or an external PACS.

Selecting Images for On-Demand Routing
VistARad’s Route Request dialog is used to select the exams to be routed on-demand and
to indicate where exams are to be sent. When a user accepts the settings in the Route
Request dialog, the exams are checked by VistARad to see if they can be routed (images
present, available in short-term storage, etc.). Then entries for each image in the selected
exams are added to the transmission queue.
Once an exam has been added to the transmission queue, on-demand routing functions in
the same way as autorouting.
This figure illustrates on-demand routing being initiated from the site with a local Routing
Gateway. On-demand routing can also be initiated from a destination site, as long as the
destination site is logged into the location (division) where the exams to be routed were acquired.
