If you are trying to set the "Rescale Intercept" (0028,1052) and "Rescale Slope" (0028,1053), set IsRescaleSlopeIntercept to true, and populate RescaleIntercept and DicomModalityLutAttributes.RescaleSlope with the new values. You can also populate RescaleType if you want to set "Rescale Type" (0028,1054).
If you are trying to set the elements under "Modality LUT Sequence", set IsModalityLutSequence to true, and populate FirstStoredPixelValueMapped, NumberOfEntries, EntryBits, and LutType. In this case, data should hold the "LUT Data" (0028,3006).
