This type is used by other structures to define a lookup table (LUT) descriptor.

Member

Description

uStructSize

The size of the structure (use sizeof(DICOMLUTDESCRIPTOR)).

uNumberOfEntries

The first value in the "LUT Descriptor". Specifies the number of entries in the lookup table.

nFirstStoredPixelValueMapped

The second value in the "LUT Descriptor". Specifies the first input value mapped.

uEntryBits

The third value in the "LUT Descriptor". Specifies the number of bits for each entry in the LUT Data.

Comments

This structure is used by the L_ApplyVOILUT and the L_ApplyModalityLUT to describe the lookup table (LUT).

This type is currently used by DICOMMLUTATTRIBS, DICOMPALCOLORLUTATTRIBS and DICOMVOILUTATTRIBS structures to specify the "LUT Descriptor".

When used with DICOMMLUTATTRIBS it specifies the attributes of "LUT Descriptor" (0028,3002) element under the "Modality LUT Sequence" (0028,3000).

When used with DICOMPALCOLORLUTATTRIBS it specifies the attributes of "Red Palette Color Lookup Table Descriptor" (0028,1101)," Green Palette Color Lookup Table Descriptor" (0028,1102) or "Blue Palette Color Lookup Table Descriptor" (0028,1103).

When used with DICOMVOILUTATTRIBS it specifies the attributes of "LUT Descriptor" (0028,3002) element under the "VOI LUT Sequence" (0028,3010).
