Forward received instances to remote AE

Overview

Configuration

• Configure one or more Export Rule
• Configure a Remote Application Entity for each of the system(s) acting as destination(s).
• Also add a DICOM Exporter for each destination.

Also, one may modify Export task polling interval, either by :

• Using Archive UI : Go to Menu->Configuration, then on Devices page click on Edit of the dcm4chee-arc device. Go to Extensions and Edit extension of Device Extension. Again go to its Extensions and Edit extension of Archive Device. Here, the default value of the field Export Task Polling Interval may be modified as required.

• Using LDAP :

    version: 1
    dn: dicomDeviceName=dcm4chee-arc,cn=Devices,cn=DICOM Configuration,dc=dcm4che,dc=org
    changetype: modify
    add: dcmExportTaskPollingInterval
    dcmExportTaskPollingInterval: PT1M
  

Testing

Required dcm4che Tools

• storescu simulating the external object source (e.g. modality) STORESCU, from which objects are being received.
• storescp simulating the external object destination (e.g. central archive) STORESCP, to which received objects are forwarded.

Verification

1. Start STORESCP tool.

      storescp -b STORESCP:11115
   

2. Store images in archive using STORESCU tool.

      storescu -c DCM4CHEE@hostname:port /pathToStudy
