Presentation LUT Shape 
3

When present, specifies an identity transformation for the Presentation LUT such that the output of all grayscale transformations, if any, are defined to be in PValues. Enumerated Values are: IDENTITY  output is in PValues  shall be used if Photometric Interpretation (0028,0004) is MONOCHROME2 or any color photometric interpretation. INVERSE  output after inversion is in PValues  shall be used if Photometric Interpretation (0028,0004) is MONOCHROME1. When this attribute is used with a color photometric interpretation then the luminance component is in PValues.

Sp

ecifies predefined Presentation LUT shapes. Enumerated Values : IDENTITY = input to the Presentation LUT is in PValues, no further translation is necessary. LIN OD = input to Presentation LUT is in linear optical density over the range of Min Density (2010,0120) and Max Density (2010,1030). Note: LIN OD is only defined for hardcopy devices and is not applicable to softcopy devices.

Presentation LUT Shape 
1C

Specifies predefined Presentation LUT transformation. Required if Presentation LUT Sequence (2050,0010) is absent. Enumerated Values: IDENTITY  no further translation necessary, input values are PValues INVERSE  output values after inversion are PValues See C.11.6.1.2.

Presentation LUT Shape 
1C

Specifies an identity transformation for the Presentation LUT, such that the output of all grayscale transformations defined in the IOD containing this Module are defined to be PValues. Enumerated Values: IDENTITY  output is in PValues. Required if Photometric Interpretation (0028,0004) is MONOCHROME2, and BitsStored (0028,0101) is greater than 1. Note: If the VOI LUT Module is required by the IOD but no VOI LUT Sequence (0028,3010) or Window Center (0028,1050) is present, then the VOI LUT stage is an identity transformation.

Presentation LUT Shape 
1

Specifies an identity transformation for the Presentation LUT, other than to account for the value of Photometric Interpretation (0028,0004), such that the output of all grayscale transformations defined in the IOD containing this Module are defined to be PValues. Enumerated Values: IDENTITY  output is in PValues  shall be used if Photometric Interpretation (0028,0004) is MONOCHROME2. INVERSE  output after inversion is in PValues  shall be used if Photometric Interpretation (0028,0004) is MONOCHROME1. See C.8.11.3.1.2 for further explanation.
