##### DD.3.2.2.4 Behavior

The SCU uses N-GET to retrieve from the SCP the verification status and results of the applicable Machine Verification SOP Instance.

The SCP shall return the Treatment Verification Status (3008,002C) Attribute as well as the status code of the requested SOP Instance update. Treatment Verification Status shall have one of the following values:

VERIFIED = treatment verified

VERIFIED_OVR = treatment verified with at least one out-of-range value overridden

NOT_VERIFIED = verification of treatment was not successful

The VERIFIED state indicates that all required parameters have been checked and no out-of-range values have been detected. The VERIFIED_OVR state indicates that the treatment failed to verify due to one or more out-of-range values that were then overridden. NOT_VERIFIED indicates that one of more of the out-of-range values has not yet been overridden and the treatment cannot go ahead. This could be because at least one out-of-range value was detected, or one or more values required for verification were not supplied. The site- and vendor-specific configuration of the MPV determines the Attributes and ranges required for successful verification.

If the Treatment Verification Status is VERIFIED_OVR, one or more parameter occurrences shall be returned in Overridden Parameters Sequence (0074,104A), otherwise the sequence shall be empty.

If the Treatment Verification Status is NOT_VERIFIED, one or more parameter occurrences shall be returned in Failed Parameters Sequence (0074,1048), otherwise the sequence shall be empty.

See Section C.31.1.1 “Failed Parameters and Overridden Parameters” in PS3.3 for specification of how the Attribute tags and position within a sequence are encoded.

The SCP shall return the status code of the requested action. The meanings of success, warning and failure status codes are defined in Section DD.3.2.2.3.
