To reduce network traffic in multiple IMPAX cluster installations, we recommend configuring Routing Presets in Source Manager for each modality read by radiologists at remote facilities. Prefetching rules set up in the Relevant Prior Manager ensures that the appropriate prior studies are retrieved.
To optimize their availability at the closest cache location, you can route the relevant priors associated with new studies scheduled or performed at the remote site and sent to the remote image server. This reduces ad hoc retrieval of priors during core hours, improving overall system performance.
To route studies to reduce network traffic in multiple cluster installations
On the Setup tab, click Source Manager.
Switch to the Other tab.
Beside the Routing Preset list, click Routing Manager.
From the bottom of the Manager Dialog, click New.
In the Routing Preset field, type a name such as Route_Priors or RemoteSite.
From the Routing Time list, select Always.
From the Study Status list, select New.
Select the Prefetch to selected destinations checkbox.
Clear the Route to selected destinations; the If key images exist, route only the key images; and the Only route studies with key images checkboxes.
Click Save.
Under Routing Destination, click Edit.
In the Select destinations dialog, select the remote image server in the Available Destination list and click Move Left
to
add it to the Routing Destinations list.Click OK.
If required—typically it is not—create routing constraints.
Click Save.
