Enum: DICOMDeidentificationActionEnum

Action codes from DICOM PS3.15 Table E.1-1a that specify how a de-identifier treats each attribute under the Basic Application Level Confidentiality Profile. Compound codes (for example Z/D) indicate that the first action applies unless the attribute's type requires the second to maintain IOD conformance. Permissible values use the DICOM code letters, with slashes replaced by underscores in compound codes.

Permissible Values

Value	Title	Meaning	Description
D	Replace with dummy value		Replace with a non-zero length value that may be a dummy value and consistent with the VR
Z	Replace with zero-length or dummy value		Replace with a zero length value, or a non-zero length value that may be a dummy value and consistent with the VR
X	Remove		Remove the attribute, and if the attribute is a sequence, remove all sequence items and their contained attributes
K	Keep		Keep unchanged for non-sequence attributes; cleaned for sequences
C	Clean		Replace with values of similar meaning known not to contain identifying information and consistent with the VR
U	Replace UID		Replace with a non-zero length UID that is internally consistent within a set of instances
Z_D	Z unless D required		Z unless D is required to maintain IOD conformance (Type 2 versus Type 1)
X_Z	X unless Z required		X unless Z is required to maintain IOD conformance (Type 3 versus Type 2)
X_D	X unless D required		X unless D is required to maintain IOD conformance (Type 3 versus Type 1)
X_Z_D	X unless Z or D required		X unless Z or D is required to maintain IOD conformance (Type 3 versus Type 2 versus Type 1)
X_Z_U	X unless Z or U required		X unless Z or replacement of contained instance UIDs (U) is required to maintain IOD conformance (Type 3 versus Type 2 versus Type 1 sequences containing UID references)
