index
The zero-based index of the VOI LUT to retrieve. According to the DICOM standard, one or more items could exist under one VOI LUT Sequence (0028,3010); use this index to specify the item from which to retrieve the attributes.
The VOI LUT attributes.
Before calling this method, access VoiLutCount to see if a VOI LUT Sequence (0028,3010) exists in the DICOM Data Set and to obtain the number of items under that sequence. index is zero-based. If you pass 0, this method will populate DicomVoiLutAttributes with the values of the "LUT Descriptor"(0028,3002) under the first item in the "VOI LUT Sequence" and LutExplanation with the value of the "LUT Explanation" (0028,3003) element, if it exists.
