Vista Imaging Vista Routing manual Start the Evaluation Processor, Stop the Evaluation Processor

Using the Routing Gateway Routing User Guide

3 Start the Evaluation Processor

When this option is executed, the evaluation processor will begin examining routing-specific entries in the rule evaluation queue. This file is populated by Image Gateways (provided that Image Gateways are configured as part of a routing system).

The evaluation processor uses the rule evaluation queue and site-specific routing rules to determine which images are to be routed and where they are to be routed. Entries for images to be autorouted are added to the transmission queue.

Typically, a single instance of the evaluation processor can manage all images produced at the sending site. For consolidated sites, an instance of the evaluation processor should be started for each location. (In this situation, a “location” equates to an entry in the

IMAGING SITE PARAMETERS File (#2006.1).)

4 Stop the Evaluation Processor

Use this option to stop the evaluation processor. When this option is executed, a flag is set that the evaluation processor will recognize as “stop evaluating.” The evaluation processor checks this flag after analyzing each image file against the routing rules.

5 Import Routing Rules

When this option is executed, the rules in \DICOM\Dict\Route.dic will be loaded into the Routing Gateway’s local MUMPS environment. For detailed steps about importing routing rules, see page 44.

6 Purge all completed entries in the Transmission Queue

Use this option to reduce the size of the transmission queue in test installations. Executing this option will remove entries for files that have been transmitted successfully.

ÂThis option is intended for use at test sites. If this option is used, routed images will be “orphaned” at a destination—rather than being deleted automatically (after the defined retention period); the images will remain until deleted manually.

To purge completed entries without orphaning routed images, use the option described in the next section.
