## Member Data Documentation

## m_SegmentationAlgorithmIdentification

AlgorithmIdentificationMacro DcmSegment::m_SegmentationAlgorithmIdentification

private

Segmentation Algorithm Identification (SQ, 1, 3).

This attribute has earlier been named m_SegmentationSurfaceGenerationAlgorithmIdentification representing the related sequence. This has been changed in favor of the Segmentation Algorithm Identification Sequence due to DICOM CP-1597.

## m_SegmentNumber

DcmUnsignedShort DcmSegment::m_SegmentNumber

private

The segment number as read from the Segment Number attribute.

This attribute only holds the number read from the file/item, and will be updated only during a write process. It is not meant to be used by the API user at all but only for internal purposes.
