Routing User Guide 

Routing Overview 

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.

 On-demand routing can also be used to 

transfer images to a DICOM destination such as a film printer or an external PACS.

Route 

Request 

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.
