Adding a DICOM Device

After adding a device to the device table with Type set to DICOM, the DICOM device setup page appears. On this page, enter the DICOM-specific configuration for the device plus the data coercion rules applied to objects received from this device. Administrators can limit the maximum number of outbound send tasks and inbound registration tasks associated with a specific device. These typically do not require changes. To change the settings from this page, in the Task Limits section enter values into the following fields, as needed.

Setting	Description
Maximum	The maximum number of tasks the system can run at one to for any inbound or outbound operation associated with this device
DICOM Out	The maximum number of outgoing DICOM (ObjectForward) tasks the system can run at one time to this device. Configurable for parent and child devices only
HTTP Out	The maximum number of outgoing HTTP (e.g., StudySynchronizer) tasks the system can run at one time to this device. Configurable for parent and child devices only
Store Date In	The maximum number of Storescpreg tasks the system can run for incoming data from this device at any point in time. Configurable for DICOM, parent and child devices only.
Registration	The maximum number of Dcreg tasks the system can spawn for incoming data from this device at any point in time. Configurable for DICOM, parent and child devices only.

In the DICOM Setting table, select the supported DICOM services of the external device, enter the DICOM AE Title, and change the send and receive timers. To use the default timer settings (See: DICOM Server) assigned to this server, enter an asterisk (*) in the text boxes.

The services are as follows:

Service	Description
AutoGet, AutoRtv	Search this device for prior studies. AutoGet uses C-GET DIMSE service. AutoRtv uses C-MOVE DIMSE service. Select only one, preferably AutoRtv
AutoFwd	Send a copy of every DICOM object received to the associated device.
UnEdit	Disallow editing of retrieved prior studies
Store	Support Storage SOP classes
Q/R	Support Query/Retrieve SOP class
MWL	Support Modality Worklist SOP class
ResMan	Support a collection of Study and Result Management SOP classes for exchanging RIS information
Commit	Support Storage Commitment SOP class
MPPS	Support Modality Performed Procedure Step SOP class

The Additional DICOM Settings section displays the DICOM-specific settings for the device. The System Settings column displays these current settings, which default to the DICOM Server Settings (See: DICOM Server)

The following attributes can be configured on a per device basis:

Attribute	Description
Transfer syntax	Preferred/supported transfer syntax
Storescu flag	Flags to be passed to storescu (i.e., storage SCU application)
Case sensitive	DICOM Q/R search is case sensitive
Empty matching	Empty value matches anything in Q/R queries
Remove private tags	Remove private EP tags when forwarding to this device
Query/Retrieve limit	Cancel the Q/R request if the number of responses exceeds this limit.
Send timeout	Time to wait for acknowledgement of a sent PDV (packet)
Receive timeout	Time to wait for next received PDV (packet)
Connection timeout	Time to wait for acknowledgement of connection request
Wait timeout	Time to wait for next C-MOVE response message to arrive
Sending updates	Automatically send modifications made to studies previously forwarded to this device
Associate heartbeat	System default setting for keeping DICOM associations open between transmission requests.
Propagate permanent delete requests	Propagate or withhold propagating permanent (Immediate) delete requests to this device. Available for devices whose Type is not Parent, Child or Backup Target. The default is defined by the Sending Updates setting.
Hard edit	Coerce edited values into their respective DICOM fields when forwarding. Auto coerces data if the DICOM negotiation fails to establish a presentation context supporting eRAD’s private SOP class.
Time zone	Time zone of the device’s clock.
Trigger outbound HL7 report messages	Inbound report objects acquired from other eRAD PACS systems initiate outbound HL7 update messages.
CD Writer	If set to Yes, the device is a DICOM File Set Creator (FSC), capable of creating DICOM media. As a result, the processed data used by the CD viewer to load quickly is included in the enhanced SR object sent to the device.
Supported Storage SOP Classes	The DICOM Storage SOP Classes eRAD PACS accepts or offers when communicating with this device. When requesting an association for sending, this list is used when proposing all available presentation contexts, meaning the –R option is not specified. To configure, click the Edit button in the Current Value column.
