No extended negotiation is performed, though STORAGE-SCP:

STORAGE-SCP provides standard conformance to the Storage Service Class.

When displaying an image in the viewing application, if a Hanging Protocol Instance is not being applied or the instance being applied does not contain presentation intent attributes, the newest Grayscale Softcopy Presentation State containing references to the image will be automatically applied, and the GSPS Presentation Label and Presentation Description will be displayed. The user has the option to select any other Presentation States that also reference the image. If no Presentation State references the image then no Presentation State will be applied by default. If a Hanging Protocol Instance is being applied, the presentation intent attributes, if present, are used to select the closest matching GSPS instance to apply. If there is no GSPS instance, then the Hanging Protocol Instance presentation intent attributes are applied, if present.

All of the Image Storage SOP Classes listed in Table G.4.2-1 are supported as references from instances of the Grayscale Softcopy Presentation State Storage SOP Class.

STORAGE-SCP provides standard conformance to the Hanging Protocol Storage Service Class.

If Partial Data Display Handling (0072,0208) is zero length, then MAINTAIN_LAYOUT behavior is applied. If the value is ADAPT_LAYOUT, then Image Boxes are proportionally resized to occupy all available display space.

If the display environment of a Hanging Protocol Instance differs from the display environment of the ImageViewer, then the layout is maintained.

The Hanging Protocol SOP instances are stored to a local database until explicitly deleted. When a study is selected for display, the application automatically applies a Hanging Protocol Instance to the study.

STORAGE-SCP will always accept any Presentation Context for the supported SOP Classes with the supported Transfer Syntaxes. More than one proposed Presentation Context will be accepted for the same Abstract Syntax if the Transfer Syntax is supported, whether or not it is the same as another Presentation Context.

STORAGE-SCP prefers explicit Transfer Syntaxes. If offered a choice of Transfer Syntaxes in a Presentation Context, it will apply the following priority to the choice of Transfer Syntax:

STORAGE-SCP will accept duplicate Presentation Contexts, that is, if it is offered multiple Presentation Contexts, each of which offers acceptable Transfer Syntaxes, it will accept all Presentation Contexts, applying the same priority for selecting a Transfer Syntax for each.

STORAGE-SCP will behave as described in the Table below when generating the C-STORE response command message.

No extended negotiation is performed.

STORAGE-SCU provides standard conformance to the Storage Service Class.

STORAGE-SCU provides standard conformance to the Hanging Protocol Storage Service Class.

In Hanging Protocol Instances created on the Viewer, no Private Attributes are used as the value of Selector Attribute (0072,0026) in any of the Sequence Attributes to which it applies.

STORAGE-SCU does not accept associations.

STORAGE-SCU prefers explicit Transfer Syntaxes. If offered a choice of Transfer Syntaxes in the accepted Presentation Contexts, it will apply the following priority to the choice of Presentation Context to use for the C-STORE operation:

STORAGE-SCU will behave as described in the Table below in response to the status returned in the C-STORE response command message.

No extended negotiation is performed.

FIND-SCU provides standard conformance to the supported C-FIND SOP Class.

The following applies to Hanging Protocol Information Model C-FIND.

If present in the response, Specific Character Set will be used to identify character sets other than the default character set for matching between Hanging Protocol and Image Instances.

FIND-SCU does not accept associations.

FIND-SCU prefers explicit Transfer Syntaxes. If offered a choice of Transfer Syntaxes in the accepted Presentation Contexts, it will apply the following priority to the choice of Presentation Context to use for the C-FIND operation:

FIND-SCU will behave as described in Table G.4.2-19 in response to the status returned in the C-FIND response command message(s).

No extended negotiation is performed.

MOVE-SCU provides standard conformance to the supported C-MOVE SOP Class.

No CANCEL requests are ever issued.

The retrieval is performed from the AE that was specified in the Retrieve AE attribute returned from the query performed by FIND-SCU. The instances are retrieved to the current application's local database by specifying the destination as the AE Title of the STORE-SCP AE of the local application. This implies that the remote C-MOVE SCP must be preconfigured to determine the presentation address corresponding to the STORE-SCP AE. The STORE-SCP AE will accept storage requests addressed to it from anywhere, so no pre-configuration of the local application to accept from the remote AE is necessary (except in so far as it was necessary to configure FIND-SCU).

MOVE-SCU does not accept associations.

MOVE-SCU prefers explicit Transfer Syntaxes. If offered a choice of Transfer Syntaxes in the accepted Presentation Contexts, it will apply the following priority to the choice of Presentation Context to use for the C-MOVE operation:

MOVE-SCU will behave as described in the Table below in response to the status returned in the C-MOVE response command message(s).

Since the C-MOVE operation is dependent on completion of C-STORE sub-operations that are occurring on a separate association, the question of failure of operations on the other association(s) must be considered.

MOVE-SCU completely ignores whatever activities are taking place in relation to the STORAGE-SCP AE that is receiving the retrieved instances. Once the C-MOVE has been initiated it runs to completion (or failure) as described in the C-MOVE response command message(s). There is no attempt by MOVE-SCU to confirm that instances have actually been successfully received or locally stored.

Whether or not completely or partially successfully retrievals are made available in the local database to the user is purely dependent on the success or failure of the C-STORE sub-operations, not on any explicit action by MOVE-SCU.

Whether or not the remote AE attempts to retry any failed C-STORE sub-operations is beyond the control of MOVE-SCU.

If the association on which the C-MOVE was issued is aborted for any reason, whether or not the C-STORE sub-operations continue is dependent on the remote AE; the local STORAGE-SCP will continue to accept associations and storage operations regardless.
