Vista Imaging Vista Routing - Manual (Page 92)

Glossary Routing User Guide
routing In the VistA system, the process responsible for sending images across a WAN
to one or more remote locations. Routing can be performed automatically (autorouting),
or on-demand.
Routing Gateway A computer running the DICOM Gateway software that is
configured to manage the routing of images in the VistA system. A Routing Gateway is
typically run on a dedicated computer. Also, the set of menu options in the DICOM
Gateway software specific to routing.
routing rules The information used by the Routing Gateway to select images for
autorouting. Routing rules are defined in a text file and are imported into a MUMPS table
used by the Routing Gateway.
routing system All of the software and hardware components related (but not
necessarily limited to) routing. Parts of the routing system include the Routing Gateway,
Image Gateways, and VistARad workstations.
rule evaluation queue The queue used to determine if newly acquired images will be
autorouted or not. This queue is populated by Image Gateways. Entries in this queue are
compared to routing rules by the evaluation processor. Entries that meet the criteria in
routing rules are added to the transmission queue.
SCU_List.dic A dictionary file used by the DICOM Gateway that contains information
about each DICOM Storage SCP that can receive DICOM images from VistA Imaging.
DICOM Storage SCPs in this file can receive DICOM images sent automatically as a
function of routing, or sent manually using a menu option on the DICOM Gateway.
SEND QUEUE (#2006.035) The FileMan file where transmission queue entries are stored.
sending site The site where routed images are produced. The Routing Gateway resides
at and is maintained by the sending site.
storage folder The physical storage location provided by an Imaging destination. A
storage folder must be referenced in a destination entry in the
NETWORK LOCATION File.
transmission background processor The original name of the transmission processor
in test versions of the routing software. There is no relationship between the transmission
background processor and the Background Processor.
transmission processor The Routing Gateway process responsible for processing
entries in the transmission queue, and for purging obsolete routed image files from
routing destinations.
transmission queue The queue used by the transmission processor to send routable
images to their destinations. Each entry in this queue represents a single image file.
Entries are added to this queue by the evaluation processor (for autorouting) or by
VistARad (for on-demand routing). Processed entries can be purged from this queue
using a Routing Gateway menu option.
