The members of this structure represent the set of attributes that describe a DICOM waveform annotation.

Member Description
uStructSize The size of the structure (use sizeof (DICOMWAVEFORMANNOTATION) )
pszUnformattedTextValue Character string that contains the "Unformatted Text Value" (0070,0006) element. If this member is not NULL, then pCodedName, pCodedValue, pNumericValue and uNumericValueCount will be ignored.
pCodedName A pointer to a structure of type DICOMCODESEQUENCEITEM which represents the single item that is included under the "Concept Name Code Sequence" (0040,A043) in the "Waveform Annotation Module". Ignored if pszUnformattedTextValue is not NULL.
pCodedValue A pointer to a structure of type DICOMCODESEQUENCEITEM which represents the single item that is included under the "Concept Code Sequence" (0040,A168) in the "Waveform Annotation Module". Ignored if pszUnformattedTextValue is not NULL.
pNumericValue A pointer to a buffer that represents the values under the "Numeric Value" (0040,A30A) element, the size of this buffer should be the same as uNumericValueCount. Ignored if pszUnformattedTextValue is not NULL.
uNumericValueCount Size of the pNumericValue buffer. Ignored if pszUnformattedTextValue is not NULL.
pMeasurementUnits A pointer to a structure of type DICOMCODESEQUENCEITEM which represents the single item that is included under the "Measurement Units Code Sequence" (0040,08EA) in the "Waveform Annotation Module".
uTemporalRangeType Value of the "Temporal Range Type" (0040,A130) element. Possible value are:
  Member Description
  DICOM_TEMPORAL_RANGE_TYPE_UNDEFINED [0x00] Undefined.
  DICOM_TEMPORAL_RANGE_TYPE_POINT [0x01] POINT (a single temporal point)
  DICOM_TEMPORAL_RANGE_TYPE_MULTIPOINT [0x02] MULTIPOINT (multiple temporal points)
  DICOM_TEMPORAL_RANGE_TYPE_SEGMENT [0x03] SEGMENT (a range between two temporal points)
  DICOM_TEMPORAL_RANGE_TYPE_MULTISEGMENT [0x04] MULTISEGMENT (multiple segments, each denoted by two temporal points)
  DICOM_TEMPORAL_RANGE_TYPE_BEGIN [0x05] BEGIN (a range beginning at one temporal point, and extending beyond the end of the acquired data)
  DICOM_TEMPORAL_RANGE_TYPE_END [0x06] END (a range beginning before the start of the acquired data, and extending to (and including) the identified temporal point).
pRefSamplePositions Pointer to a buffer that represents the values under the "Referenced Sample Positions" (0040,A132) element, the size of this buffer should be the same as uTemporalPointCount. This parameter is ignored if uTemporalPointCount is 0.
pRefTimeOffsets Pointer to a buffer that represents the values under the "Referenced Time Offsets" (0040,A138) element, the size of this buffer should be the same as uTemporalPointCount. This parameter is ignored if uTemporalPointCount is 0 or if pRefSamplePositions is not NULL.
pRefDatetime Pointer to an array of type VALUEDATETIME that represents the values under the "Referenced Datetime" (0040,A13A) element, the size of this buffer should be the same as uTemporalPointCount. This parameter is ignored if uTemporalPointCount is 0 or if either pRefSamplePositions or pRefTimeOffsets is not NULL.
uTemporalPointCount Size of the buffers pointed to by pRefSamplePositions, pRefTimeOffsets and pRefDatetime.
puAnnGroupNumber Pointer to a value that contains the "Annotation Group Number" (0040,A180) element. To ignore Set to NULL, to ignore.

Comments

This data type is based on the attributes of the "Waveform Annotation Module" and is mainly used with the functions LDicomWaveformChannel::GetAnnotation and LDicomWaveformChannel::AddAnnotation to support waveform annotations.
