Defining DICOM Destinations
In general terms, defining a DICOM destination breaks down into the following steps:
1 Determine the names that will be used to identify the destination and gather
information about the receiving application.
2 Edit the SCU_List.dic file, a dictionary file used by the DICOM Gateway(s).
3 Use the DICOM Gateway to load the contents of SCU_List.dic into the MUMPS
databases on the DICOM Gateway and on the VistA Host.
The three following sections explain in detail how each general step is performed. A
destination definition worksheet is located on page
73 .
Note: A DICOM destination must be a DICOM Storage SCP (Service Class Provider).
For information about defining Imaging (VistARad) destinations, see page
26 .
Naming Conventions for DICOM Destinations
The first step in defining a DICOM destination is determining what to name the
destination and how to identify the sender of DICOM images.
ƒ When selecting a destination name (entered as the Application in SCU_List.dic), be
sure that the name is 31 characters or less in length (case insensitive, punctuation is
allowed), and that the name does not match any name defined for an Imaging
destination.
ƒ The sender of DICOM images (Calling AE in SCU_List.dic) is the ‘Transmit DICOM
Images to a DICOM SCP’ function of the DICOM Gateway. The name used to
identify this function needs to be agreed on by the sender and receiver of the DICOM
transmission.
The remaining information needed to define a DICOM destination is determined by the
system that will be receiving the routed images. This information is described in detail
on page
39 .
DICOM Destination Definitions in SCU_List.dic
This section explains how to update SCU_List.dic specifically for the purposes of
routing, and how to load the contents of SCU_List.dic into the DICOM and VistA system
databases. The steps below assume that a single instance of SCU_List.dic is used by all
DICOM Gateways at a site.
Adding DICOM Destinations to SCU_List.dic
1 Stop all active DICOM processes by waiting until they reach an idle state, and then
terminating them.
