DICOM device settings


 

The DICOM services table defines the supported DICOM services of each external device. Enter the DICOM AE Title, change send and receive timers, check supported services, and save.

 

The services supported are as follows:

 

AutoGet, AutoRtv: Search this device for prior studies. AutoGet uses C-GET DIMSE service. AutoRtv uses C-MOVE DIMSE service. Unless explicitly required by the device, use AutoRtv instead of AutoGet for all devices.

AutoFwd: Send a copy of every DICOM object received to this device.

UnEdit: Disable editing of studies retrieved from this device.

Store: Device supports storage SOP classes as an SCU (U) and/or SCP (P).

Q/R: Device supports query/retrieve SOP class as an SCU (U) and/or SCP (P).

MWL: Device supports modality worklist SOP class as an SCU (U) and/or SCP (P).

ResMan: Device supports a collection of study and result management SOP classes.

Commit: Device support storage commitment SOP class as an SCP (P).

MPPS: Device supports modality performed procedure step SOP class as an SCP (P).

 

For the DICOM SOP Classes, one or two columns exist. A check in the U column indicates the device supports the SCU of the SOP class. A check in the P column indicates the device is an SCP. eRAD PACS accepts the SOP class during association negotiation only if the checkbox is checked.  To prevent supporting the SOP class, clear the check box.

 

Some DICOM device settings can be customized for each DICOM device. These are set in the Additional DICOM Settings section.  The System Settings column displays the current default settings. The Current Value column allows you to override each attribute by entering a new value and selecting the checkbox, or choosing a new value from the drop-down list. The following attributes can be configured on a per device basis:

 

Transfer syntax: preferred/supported transfer syntax.

Storescu flag: flags to be passed to storescu.

Case sensitive: DICOM Q/R search is case sensitive.

Empty matching: empty value matches anything in Q/R queries.

Remove private tags: when forwarding to this device, remove all private tags.

Query/Retrieve limit: when sending QR query to the device, cancel the 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 additional modifications made to studies previously forwarded to this device.

Supported storage  SOP classes: The DICOM Storage SOP classes EP supports. The list applies to EP as both an SCU and SCP, meaning it affects the SOP Classes EP requests or accepts in a DICOM Association Request or Response.

 

The data coercion section of the DICOM device settings define rules for modifying DICOM attributes when the object first arrives on the server.  Refer to the data coercion section for details.
