} DICOMWAVEFORMANNOTATION, * pDICOMWAVEFORMANNOTATION; 

Members

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:

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.

Usage

• LDicomWaveformChannel::AddAnnotation
• LDicomWaveformChannel::GetAnnotation
