DicomModalityLutAttributes Class

The DicomModalityLutAttributes is used by the methods DicomDataSet.GetModalityLutAttributes and DicomDataSet.SetModalityLut to get and set the attributes that describe the Modality LUT.

Remarks

The properties of this class are based on the attributes of the "Modality LUT Module". Please see "Modality LUT Module Attributes" in the DICOM standard for more details.
The DICOM standard states that:

"Either a Modality LUT Sequence containing a single Item or Rescale Slope and Intercept values shall be present, but not both."

For this reason, both IsModalityLutSequence and IsRescaleSlopeIntercept cannot be set to true at the same time.
When using this class with the DicomDataSet.SetModalityLut method you must set one of the flags, either IsModalityLutSequence or IsRescaleSlopeIntercept. If you set IsModalityLutSequence, you must populate IsModalityLutSequence, LutExplanation and LutType with valid values. If you set IsRescaleSlopeIntercept, you must populate RescaleIntercept, RescaleType with valid values.
According to the DICOM standard when the number of table entries under the "LUT Data" (0028,3006) element is equal to 2^16 then the value of FirstStoredPixelValueMapped, NumberOfEntries and EntryBits. NumberOfEntries shall be 0. However, the 2 methods, DicomDataSet.GetModalityLutAttributes and DicomDataSet.SetModalityLut, do NOT have this limitation. When you call DicomDataSet.GetModalityLutAttributes, it will automatically set value in the dataset to 0 if NumberOfEntries is equal to 2^16. The same applies to DicomDataSet.SetModalityLut.

Example

For an example, refer to DicomDataSet.GetModalityLutAttributes.
