2.2.1.2.3Asynchronous Nature

Table 2.2-5: Asynchronous Nature as an Association Initiator for DICOM Store AE

Maximum number of outstanding asynchronous transactions

1

The DICOM Store AE allows a single outstanding operation on any association. Therefore, it does not support asynchronous operations window negotiation, other than the default as specified by the DICOM specification.

2.2.1.3Association Initiation Policies

2.2.1.3.1Activity – Send Images

2.2.1.3.1.1Description and Sequencing of Activity

A user can select an image and request it to be sent to a destination The request is forwarded to the job queue and then processed. An image can also be sent automatically when closing an exam.

Note:

An image can only be sent to an archiving destination if it hasn’t been archived there yet.

The DICOM Store AE is then invoked by the queue that is responsible for processing network archival tasks for a specific destination. The DICOM Store AE will attempt to initiate a new Association in order to issue a C-STORE request. If the job contains multiple images, then multiple C-STORE requests will be issued over the same Association. The association will be closed when the last image (or GSPS) is sent.

If the association cannot be opened, the job is set to a retry state. If after a configurable number of retries the job still fails, it is set to an error state (“Failed”). It can then be restarted by the user through the job control interface. If three successive jobs to a same destination fail, the queue for that destination will be stalled. It will retry to process the job three (3) more times. If this fails, the queue for that destination will be stalled for a longer time, meaning that it will only retry jobs to that destination every five (5) minutes.

When the association was rejected by the device due to a configuration issue, the queue for that device will be stalled when three (3) successive jobs experience a device failure.

If the Remote AE is configured to support Storage Commit, the DICOM Store AE will send a Storage Commit request (N-ACTION) over a new association and will then wait for an N-EVENT-REPORT. If the N-EVENT- REPORT does not arrive within the waiting period, the AE closes the association and assumes that a separate association will be set up for the N-EVENT-REPORT. If this report does not arrive within a (configurable) amount of time, the job will be marked as FAILED.

1XX is the build version number.
