DICOM PDQ Service

A DICOM PDQ Service searches for patient demographics for patient(s) available on an external C-FIND SCP.

Configuration

Ensure to create a Remote Application Entity for external archive or external C-FIND SCP.

Using Archive UI

• Go to Menu -> Configuration -> Devices -> dcm4chee-arc -> Extensions -> Edit extension -> Device Extension -> Archive Device Extension -> Child Objects -> PDQ Service.
• Enter values for PDQ Service ID, PDQ Service Description and Patient Attributes as required.
• Specify PDQ Service URI as pdq-dicom:EXTERNAL_ARCHIVE_AET. (Note that EXTERNAL_ARCHIVE_AET here is the Remote AE acting as C-FIND SCP.)
• Add mandatory PDQ Service Property as LocalAET=DCM4CHEE (Note : If default archive AE DCM4CHEE is changed/renamed, specify the value here accordingly) and Save.

Using LDAP

One may either

• create a LDIF file (e.g.):

    version: 1       
    dn: dcmPDQServiceID=Test PDQ,dicomDeviceName=dcm4chee-arc,cn=Devices,cn=DICOM Configuration,dc=dcm4che,dc=org
    objectClass: dcmPDQService
    dcmPDQServiceID: Test PDQ
    dcmURI: pdq-dicom:EXTERNAL_ARCHIVE_AET
    dicomDescription: Test PDQ with External Archive
    dcmTag: 00100010
    dcmTag: 00100030
    dcmTag: 00100040
    dcmProperty: LocalAET=DCM4CHEE 
    -
  

and import it to the LDAP Server by using the ldapadd command line utility or the LDIF Import... function of Apache Directory Studio

• or directly use the New Entry... function to create corresponding Exporter entries.

One may refer to PDQ Service to understand the description of attributes.

Go to the Control tab on Configuration page in archive UI and reload the configuration.
