6.3.1.2.1.2.1 SOP Specific DICOM Conformance Statement for the Worklist SOP Class

If the remote AE does not support the proposed Presentation Context, an appropriate error is

logged and the operator is notified.

This implementation can receive multiple C-FIND results over a single association. Only one

association is opened at a time.

Each C-FIND response received from the remote AE is parsed to verify the length/type of the

items in the response). Upon detecting any error in the response data, the Worklist Server AE

will save worklist entry in binary format for investigative purposes and the Worklist Server AE

will continue receiving worklist entries. Note: All worklist entries, valid and invalid, can be

configured to be saved in binary format.

On receipt of any error from the remote AE, the Worklist Server will issue a C-FIND-CANCEL

and, upon receipt of a C-FIND-RSP (or if an applicable timer expires), will abort the association.

All previously received worklist items are retained. Warnings received from the remote AE are

ignored.

Each C-FIND operation supports a configurable “Association Timer.” This timer starts when the

association request is sent or received and stops when the association is established. The

default time-out value is 30 seconds.

Each C-FIND operation supports a configurable “Session Timer.” This timer starts when an

association is established and stops when the association is ended. The default time-out value

is 3600 seconds.

If any of the above timers expires, the association is aborted (A-ABORT) and the operation in

progress is considered to be failed. Any previously received worklist items are discarded.
