SCP_SCU_RoleSelectionNegotiation
¶ A representation of the SCP/SCU Role Selection Negotiation primitive.
Allows peer AEs to negotiate the roles in which they will serve for each SOP Class or Meta SOP Class supported on the Association. This negotiation is optional.
The Association Requestor may use one SCP/SCU Role Selection item for each SOP Class as identified by its corresponding Abstract Syntax Name and shall be one of three role values:
- Requestor is SCU only
- Requestor is SCP only
- Requestor is both SCU/SCP
If the SCP/SCU Role Selection item is absent the default role for a Requestor is SCU and for an Acceptor is SCP.
For a Requestor support for each SOP Class shall be one of the following roles:
- Requestor is SCU only
- Requestor is SCP only
- Requestor is both SCU and SCP
Identical for both A-ASSOCIATE-RQ and A-ASSOCIATE-AC
-
sop_class_uid
¶ The UID of the corresponding Abstract Syntax
Type: pydicom.uid.UID, bytes or str
-
scu_role
¶ False for non-support of the SCU role, True for support
Type: bool
-
scp_role
¶ False for non-support of the SCP role, True for support
Type: bool
Examples
>>> from pynetdicom.pdu_primitives import SCP_SCU_RoleSelectionNegotiation >>> item = SCP_SCU_RoleSelectionNegotiation() >>> item.sop_class_uid = '1.2.840.10008.5.1.4.1.1.2' >>> item.scu_role = True >>> item.scp_role = False
