Example

This example will set the modality LUT information inside a DICOM dataset.

Public Sub TestSetModalityLut()

}

Remarks

This method will set the attributes of the "Modality LUT Module".

If you are trying to set the "Rescale Intercept" (0028,1052) and "Rescale Slope" (0028,1053), set IsRescaleSlopeIntercept to true, and populate RescaleIntercept and 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).

Requirements

Target Platforms: Microsoft .NET Framework 2.0, Windows 98, Windows NT 4.0, Windows Millennium Edition, Windows 2000, Windows XP Home Edition, Windows XP Professional, Windows Server 2003 family
