Note
-
SOP Class UID (0008,0016) is an optional key, but it is strongly recommended that it always be returned by all SCPs, if matching is requested.
-
The Concept Name Code Sequence (0040,A043) and Content Template Sequence (0040,A504) are optional keys that are useful for identifying instances of various Structured Reporting Storage SOP Classes. It is strongly recommended that these keys be supported by the SCP for query against such instances.
The Alternate Representation Sequence (0008,3001) encodes a reference to an alternate encoding of the composite image identified in the Query response item. This alternate encoding may utilize a different SOP Class or have different image quality characteristics, but it shall be the same image.
Note
The Alternate Representation Sequence (0008,3001) allows the query response about an original image to reference a lossy compressed version, and vice versa.
An image may be lossy compressed, e.g., for long-term archive purposes, and its SOP Instance UID changed. An application processing a SOP Instance that references the original image UID, e.g., a Structured Report, may query the C-FIND SCP for the image. The SCP returns a reference to an accessible version of the image even if the original SOP Instance is no longer available.
The Alternate Representation Sequence (0008,3001), if present in a Query Request Identifier, shall be zero-length, or shall contain a single zero-length Item. That is, only Universal Matching is defined for this Attribute.
The Alternate Representation Sequence (0008,3001), if present in the Query Response Identifier, may include zero or more Items. Each Alternate Representation Sequence Item in the Query Response Identifier shall include
-
the Series Instance UID (0020,000E) if the alternately encoded image is in a different Series.
-
the SOP Class UID (0008,0016) and SOP Instance UID (0008,0018) of the alternately encoded image.
-
the Purpose of Reference Code Sequence (0040,A170), which shall describe the nature of the alternate encoding of the image. The Purpose of Reference Code Sequence (0040,A170) shall include only one Item. The Baseline Context Group for this Code Sequence is CID 7205.
A C-MOVE or C-GET request may be performed to any level of the Query/Retrieve Model. However, the transfer of Stored SOP Instances shall always take place at the Composite Object Instance level. A C-MOVE or C-GET where the Query/Retrieve level is the:
-
PATIENT level indicates that all Composite Object Instances related to a Patient shall be transferred.
-
STUDY level indicates that all Composite Object Instances related to a Study shall be transferred.
-
SERIES level indicates that all Composite Object Instances related to a Series shall be transferred.
-
IMAGE level indicates that selected individual Composite Object Instances shall be transferred.
Note
In the Baseline behavior, more than one entity may be retrieved if the Query/Retrieve Level is IMAGE, SERIES or STUDY, using List of UID matching, but only Single Value Matching value may be specified for Patient ID (0010,0020).
An implementation may conform to one of the SOP Classes of the Patient Root SOP Class Group as an SCU, SCP or both. The Conformance Statement shall be in the format defined in PS3.2.
An implementation that conforms to one of the SOP Classes of the Patient Root SOP Class Group shall support queries against the Query/Retrieve Information Model described in Section C.6.1.1 using the baseline C-FIND SCU Behavior described in Section C.4.1.2.
An implementation that conforms to one of the SOP Classes of the Patient Root SOP Class Group as an SCU shall state in its Conformance Statement whether it supports Optional Keys. If it supports Optional Keys, then it shall list the Optional Keys that it supports.
An implementation that conforms to one of the SOP Classes of the Patient Root SOP Class Group as an SCU shall state in its Conformance Statement whether it may generate Relational-queries. If it supports Relational-queries, then it shall also support extended negotiation of relational-queries.

An implementation that conforms to one of the SOP Classes of the Patient Root SOP Class Group as an SCU shall state in its Conformance Statement how it makes use of Specific Character Set (0008,0005) and Timezone Offset From UTC (0008,0201) when encoding queries and interpreting responses.
An implementation that conforms to one of the SOP Classes of the Patient Root SOP Class Group as an SCU shall support transfers against the Query/Retrieve Information Model described in Section C.6.1.1 using the C-MOVE SCU Behavior described in Section C.4.2.2.
An implementation that conforms to one of the SOP Classes of the Patient Root SOP Class Group as an SCU shall support retrievals against the Query/Retrieve Information Model described in Section C.6.1.1 using the C-GET SCU Behavior described in Section C.4.3.2.
An implementation that conforms to one of the SOP Classes of the Patient Root SOP Class Group as an SCU, which generates retrievals using the C-GET operation, shall state in its Conformance Statement the Storage Service Class SOP Classes under which it shall support the C-STORE sub-operations generated by the C-GET.

An implementation that conforms to one of the SOP Classes of the Patient Root SOP Class Group as an SCP shall state in its Conformance Statement whether or not it supports extended negotiation of combined date-time matching and/or fuzzy semantic matching of person names. If fuzzy semantic matching of person names is supported, then the mechanism for fuzzy semantic matching shall be specified.
An implementation that conforms to one of the SOP Classes of the Patient Root SOP Class Group as an SCP shall state in its Conformance Statement whether it supports case-insensitive matching for PN VR Attributes and list Attributes for which this applies.
An implementation that conforms to one of the SOP Classes of the Patient Root SOP Class Group as an SCP shall state in its Conformance Statement how it makes use of Specific Character Set (0008,0005) and Timezone Offset From UTC (0008,0201) when interpreting queries, performing matching and encoding responses.
An implementation that conforms to one of the SOP Classes of the Patient Root SOP Class Group as an SCP shall support transfers against the Query/Retrieve Information Model described in Section C.6.1.1 using the C-MOVE SCP Behavior described in Section C.4.2.3.
An implementation that conforms to one of the SOP Classes of the Patient Root SOP Class Group as an SCP, which generates transfers using the C-MOVE operation shall state in its Conformance Statement the Storage Service Class SOP Classes under which it shall support the C-STORE sub-operations generated by the C-MOVE.
