Nonconforming Modified Attributes Sequence Attribute

Tag(0400,0551)
TypeOptional (3)
KeywordNonconformingModifiedAttributesSequence
Value Multiplicity1
Value RepresentationSequence (SQ)

Attributes that were replaced or removed from the Data Set because the values were not conformant to the Attribute's Value Representation or Value Multiplicity.

See Section C.12.1.1.9.2.

One or more Items are permitted in this Sequence, one Item for each nonconforming Attribute.

Section C.12.1.1.9.2

C.12.1.1.9.2 Nonconforming Modified Attributes Sequence

If an Attribute Value was replaced or removed because its value was nonconforming to its Value Representation or Value Multiplicity, the original value (which was replaced by a zero length value in the Modified Attributes Sequence) may be recorded in the Nonconforming Modified Attributes Sequence (0400,0551).

The nonconforming Attribute is identified by the Attributes of the Selector Attribute Macro. Because a single Attribute is being identified, Selector Attribute (0072,0026) shall be present.

The Data Set to which the Selector Attribute Macro applies is the single Item of the Modified Attributes Sequence (0400,0550) within the same Item of the Original Attributes Sequence (0400,0561). Therefore, the Modified Attributes Sequence (0400,0550) is not identified in the Selector Sequence Pointer (0072,0052).

Note

  1. This is effectively the same as a pointer to the equivalent Attribute in the original top level Data Set.

  2. Characters in text Attributes non-conformant to the identified Specific Character Set (0008,0005) may be considered non-conformant to the VR.

  3. For example, if Body Part Examined (0018,0015) had a nonconforming value, the Nonconforming Modified Attributes Sequence (0400,0551) Item would have the Attributes:

    (0072,0026)

    00180015

    Selector Attribute

    (0072,0028)

    1

    Selector Value Number

    Nonconforming Data Element Value

  4. The Nonconforming Data Element Value (0400,0552) has Value Representation OB, which allows an arbitrary byte string to be encoded.
