DICOM Server AE to retrieve the selected image(s) from the Remote DICOM AE by choosing

“Get Examination”, “Get Series”, or “Get Images”.

(4) Real-World Activity, Choose “Ping DICOM host” Option, consists of an operator selecting

“Ping DICOM host” from the “Network” pull down menu. This will cause the DICOM Server AE

to initiate a “DICOM Verification Request” to the remote AE, to verify the remote system

activeness.

(5) The Choose “storage commitment” Option Real-World activity consists of an operator

configuring the remote node as an “archive node.” Select “choose media” option under

“Archive” pull down menu. Select “Remote Node” in that menu. Select one or more study, series

or image in the local database manager and choose either “Save Exam” or “Save Series” from

the “Archive” pull down menu. This will cause the DICOM server AE to send the image(s) to the

selected destination and wait for the storage commitment from the remote node. The remote

node should be a storage commitment provider.

There is no Real-World activity required for the DICOM Server AE to respond to an incoming

DICOM store, query or retrieve. The DICOM Server AE is always prepared to respond to a

DICOM Store, Query, or Retrieve by any remote DICOM AE.

The DICOM Server AE will perform the Real-World activity Image Installation after the remote

AE sends an image to the LightSpeed product.

Once a Query request is received, the DICOM Server AE will search the local database for all

entries that match the keys requested by the Remote DICOM AE and send back the list of

matches. The DICOM Server AE will also respond to an incoming retrieval request from a

Remote AE by sending the image(s) to the Destination AE.

2.2.2 Functional Definition of AE’s

DICOM Server Application Entity initiates the following operations:

• Ping DICOM Host (Verification): The DICOM Server initiates an association and sends a C-

ECHO-RQ message to the remote DICOM AE; the remote DICOM Server will send back a

C-ECHO-RSP message with a status of “success”.

• Push: Initiate an association to a Remote AE to send image(s). If the Remote AE accepts

the presentation context applicable to the image(s) being sent, the DICOM Server AE will

send the image(s) by invoking C-STORE-RQ operation for each image on the same

association.

• Query: Initiate an association with a Remote AE to query for images on the remote host. A

Study-Root Study-Level C-FIND-RQ request will be sent to the Remote AE once an

association has been established. After all responses are received, DICOM Server AE will

issue a Series-Level C-FIND-RQ request to get the series for a study in the list. An Image-

Level C-FIND-RQ will be issued for the first series in the series list.

• Get: Send a C-MOVE-RQ request to a Remote AE after successful association

establishment. The DICOM Server AE’s Storage SCP will receive the images over a

separate association.
