The DICOM Server AE waits for association requests from Remote AEs that wish to perform
the following operations:
• Verification: If a C-ECHO-RQ message is received, the DICOM Server AE will send back a
C-ECHO-RSP message with a status of “success”.
• Image Storage: If a C-STORE-RQ message is received, the DICOM Server AE will receive
the image and try to update the local database. If the image is stored successfully on
storage media and the database updated a status of “success” will be returned in a C-
STORE-RSP message.
• Query: If a C-FIND-RQ message is received the DICOM Server AE will search the database
for the requested attributes and send back a C-FIND-RSP message containing a match and
a status of “pending”. After all matching records have been sent, a status of “success’ will be
returned in a C-FIND-RSP message. The Remote AE can terminate the query by sending a
C-CANCEL-FIND-RQ message.
• Retrieve: If a C-MOVE-RQ message is received the DICOM Server AE will lookup its list of
configured Remote AEs for the Destination AE. If the Destination AE is configured, the
DICOM Server AE will open a new association to the Destination AE and use C-STORE-RQ
to send the image(s). The DICOM Server AE will send a C-MOVE-RSP message with a
status of “pending” after every five images are sent. When all images are sent or if DICOM
Server AE receives a C-CANCEL-MOVE-RQ a final C-STORE-RSP will be sent back with
an appropriate status.
