Note: Use of Retired SOP Classes only is user configurable for the system on the PSC – Network/DICOM – DICOM Settings – DICOM Storage Device – Advanced Settings configuration page. All image storage will use Retired SOP Classes only when selected. 4.2.1.2 Association Establishment Policy 4.2.1.2.1 General The DICOM standard application context name for DICOM 3.0 is always proposed: Table 4.2 DICOM APPLICATION CONTEXT FOR AE STORAGE Application Context Name 1.2.840.10008.3.1.1.1 4.2.1.2.2 Number of Associations EPIQ/Affiniti initiate s one Association at a time for each destination to which a transfer request is being processed in the active job queue list. Five storage destinations, one Structured Report storage destination, and one Storage Commitment destination may be selected simultaneously, but only one job will be active at a time; the other(s) remain pending until the active job is completed or failed. Table 4.3 NUMBER OF ASSOCIA TIONS INITIATED FOR AE STORAGE Maximum number of simultaneous Associations 1 EPIQ/Affiniti accept s Associations for N -EVENT -REPORT notifications for the Storage Commitment Push Model SOP Class. EPIQ/Affiniti will also accept Associations for C -STORE messages for receiving data in response to Query/Retrieve C-MOVE requests or unsolicited images from a remote Storage SCU sending images to EPIQ/Affiniti. Table 4.4 NUMBER OF ASSOCI ATIONS ACCEPTED FOR AE STO RAGE Maximum number of simultaneous Associations 5 4.2.1.2.3 Asynchronous Nature EPIQ/Affiniti does not support asynchronous communication (multiple outstanding transactions over a single Association).

Reports may not be selected individually, but are sent when “End Exam” is pressed, and when an entire exam is selected for export from the Review Directory and exported to a Storage device with “Export St ructured Report” enabled. Each object ( image, private presentation state, or structured report) is entered into the job queue. When send “After Each Print/ Acquire” is enabled, the acquired images are sent to the selected destinations immediately after acquisition . The Network Status icon reports the status of the job, Green is ok, Yellow is pending until a network connection is available , and Red is failed. If the C -STORE response from the remote Application Entity contains a status other than Success, the Association is aborted and the related Job is switched to a failed state. It can be restarted any time by user interaction. When a system configured with selected network destinations is used without the network connected, it is considered in “Porta ble” mode. R econnecting the network cable will initiate transfer again. If a device is configured for Storage Commitment service, the Storage AE will transmit a separate Storage Commitment N-ACTION request for images and one for the report . The Storage AE can only receive an N -EVENT - REPORT request in a separate subsequent association initiated by the SCP employing PDU 54H SCP/SCU Role Negotiation of “SCP” in the SCP’s Association Request. It cannot receive N -EVENT -REPORT request messages on the same association as the N -ACTION request . Structured reports will contain all supported measurements and calculations created by EPIQ/Affiniti even if they are not selected for display in the on- system report. One Structured Report instance is created for each template that is used. E7 and E5/A70 and A50 1.5.x.x DICOM Conformance Statement 000490000000111 Rev A Page 23

If the “At End Exam” configuration option is selected, no C -STORE is sent at the Acquire Image event and instead all image C -STOREs are sent after end exam. NOTES: Pausing an exam will close the current as sociation. A new association will be created when resumed. Similar behavior when the association times out. The N -EVENT -REPORT must be sent over a separate association initiated by the Image Manager (see Section 4.2.1.4.1 on Activity – Receive Storage C ommitment Response).

Table 4.8 describes C -Store response behavior.

Association aborted by the SCP or network layers The Association is aborted using A -ABORT and the transfer fails. The status is logged.

The Storage AE will request storage commitment for the configured device. Storage Commitment is reques ted automatically by the system immediately after the object are stored (but not necessarily one-to-one with each storage request ).
