MPPS trigger no IAN

Configuration

• Using Archive UI - Can be configured either on :

  • Archive Device level (Send IAN for instances received by any Application Entity of the Archive) :

    Go upto archive device extension level Configuration page -> Devices tab -> dcm4chee-arc -> Device Extension -> Archive Device Extension. Configure IAN Timeout and set IAN On Timeout to False and Save.

  • Archive Application Extension level (Send IAN for instances received by this Application Entity of the Archive) :

    Go upto archive AE extension level Configuration page -> Devices tab -> dcm4chee-arc -> Child Objects Network AEs -> Network AE Extension -> Archive Network AE Extension. Configure IAN Timeout and set IAN On Timeout to False and Save.

OR

• Using LDAP - One may either create a LDIF file to add attributes either on :

  • Archive Device level (e.g.):

      version: 1
      dn: dicomDeviceName=dcm4chee-arc,cn=Devices,cn=DICOM Configuration,dc=dcm4che,dc=org
      changetype: modify
      add: dcmIanTimeout
      dcmIanTimeout: PT5M
    
      dn: dicomDeviceName=dcm4chee-arc,cn=Devices,cn=DICOM Configuration,dc=dcm4che,dc=org
      changetype: modify
      add: dcmIanOnTimeout
      dcmIanOnTimeout: FALSE        
    

  OR

  • Archive AE level (e.g.):

      version: 1        
      dn: dicomAETitle=DCM4CHEE,dicomDeviceName=dcm4chee-arc,cn=Devices,cn=DICOM Configuration,dc=dcm4che,dc=org
      changetype: modify
      add: dcmIanTimeout
      dcmIanTimeout: PT5M
    
      dn: dicomAETitle=DCM4CHEE,dicomDeviceName=dcm4chee-arc,cn=Devices,cn=DICOM Configuration,dc=dcm4che,dc=org
      changetype: modify
      add: dcmIanOnTimeout
      dcmIanOnTimeout: FALSE
    

  and import it to the LDAP Server by using the ldapmodify command line utility.

  OR use the Add Attribute... and Add Value... function of Apache Directory Studio to add attributes on Device Level (e.g.: dicomDeviceName=dcm4chee-arc) or on Application Entity Level (e.g: dicomAETitle=DCM4CHEE) of the Archive Configuration.

One may refer to Archive Device or Archive Network AE to understand the description of attributes.

Refer ISO-8601 Duration format for more know-how on Durations.

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

Testing

Required dcm4che Tools

• storescu simulating the external object source (e.g. modality) STORESCU, from which objects are being received.
• mppsscu simulating Service Class User (SCU) for the Modality Performed Procedure Step (MPPS) SOP Class and for the Verification SOP Class.

Verification

1. Start IANSCP

      ianscp -b IANSCP:11117
   

2. Send MPPS request for a study

      mppsscu -c DCM4CHEE@localhost:11112 /pathToStudy
   

3. Wait for IAN Timeout to expire

4. Store all objects of that study on archive

      storescu -c DCM4CHEE@localhost:11112 /pathToStudy
