SCP
(req, context)¶ The SCP implementation for the Verification Service Class.
Will always return 0x0000 (Success) unless the user returns a different (valid) status value from the handler bound to evt.EVT_C_ECHO.
Parameters: - req (dimse_primitives.C_ECHO) – The C-ECHO request primitive sent by the peer.
- context (presentation.PresentationContext) – The presentation context that the SCP is operating under.

Notes
C-ECHO Request
Parameters
(M) Message ID(M) Affected SOP Class UIDC-ECHO Response
Parameters
(U) Message ID(M) Message ID Being Responded To(U) Affected SOP Class UID(M) StatusStatus
The DICOM Standard, Part 7 (Table 9.3-13) indicates that the Status value of a C-ECHO response “shall have a value of Success”. However Section 9.1.5.1.4 indicates it may have any of the following values:
- Success
0x0000
Success- Failure
0x0122

is_cancelled
(msg_id)¶ Return True if a C-CANCEL message with msg_id has been received.
Parameters: msg_id (int) – The (0000,0120) Message ID Being Responded To value to use to match against. Returns: True if a C-CANCEL message has been received with a Message ID Being Responded To corresponding to msg_id, False otherwise. Return type: bool
-
is_valid_status
(status)¶ Return True if status is valid for the service class.
Parameters: status (int) – The Status value to check for validity. Returns: True if the status is valid, False otherwise. Return type: bool
-
validate_status
(status, rsp)¶ Validate status and set rsp.Status accordingly.
Parameters: - status (pydicom.dataset.Dataset or int) – A Dataset containing a Status element or an int.
- rsp (dimse_primitive) – The response primitive to be sent to the peer.
Returns: rsp – The response primitie to be sent to the peer (containing a valid Status parameter).
Return type: dimse_primitive
