## EE.2 Display System SOP Class

### EE.2.1 IOD Description

The Display System IOD is an abstraction of the soft-copy display system and is the basic Information Entity to monitor the status of a Display System. The Display System SOP Instance is created by the SCP during start-up of the Display System and has a well-known SOP Instance UID.

### EE.2.2 DIMSE Service Group

The DIMSE Service shown in Table EE.2.2-1 is applicable to the Display System IOD under the Display System SOP Class.

##### EE.2.2.1.2 SCU Behavior

The SCU uses the N-GET to request the SCP to provide the contents of a Display System SOP Instance. The SCU shall specify in the N-GET request primitive the UID of the SOP Instance from which attributes are to be returned.

The SCU shall specify the list of Display System Attributes for which values are to be returned. The SCU shall not specify Attributes which are defined within a Sequence, but rather specify the sequence itself to be returned in its entirety.

The SCU shall specify in the N-GET request primitive the well-known UID of the SOP Instance.

##### EE.2.2.1.3 SCP Behavior

The SCP shall return the values for the specified Attributes of the Display System SOP Instance.

The SCP shall return the status code for the requested SOP Instance retrieval. The meaning of success, warning, and failure status codes are defined in PS3.7.

### EE.2.3 SOP Class Definitions and UIDs

The SOP Class UID of the Display System SOP class shall have the value of "1.2.840.10008.5.1.1.40".

### EE.2.4 Reserved Identifications

The well-known UID of the Display System SOP Instance shall have the value of "1.2.840.10008.5.1.1.40.1".
