LUT Descriptor Attribute

Tag(0028,3002)
TypeRequired (1)
KeywordLUTDescriptor
Value Multiplicity3
Value RepresentationUS or SS

Specifies the format of the LUT Data in this Sequence.

See Section C.8.11.3.1.5 for further explanation.

Section C.8.11.3.1.5

C.8.11.3.1.5 VOI Attributes

The Attributes of the VOI LUT Module are specialized in the DX Image Module.

Window Center (0028,1050) and Window Width (0028,1051) specify a linear conversion (unless otherwise specified by the value of VOI LUT Function (0028,1056); See Section C.11.2.1.3) from the output of the (conceptual) Modality LUT values to the input to the (conceptual) Presentation LUT. Window Center contains the value that is the center of the window. Window Width contains the width of the window.

The application of Window Center (0028,1050) and Window Width (0028,1051) shall not produce a signed result.

Note

If the Presentation LUT Shape (2050,0020) is IDENTITY, then the result of applying Window Center (0028,1050) and Window Width (0028,1051) is P-Values.

If multiple values are present, both Attributes shall have the same number of values and shall be considered as pairs. Multiple values indicate that multiple alternative views should be presented.

The VOI LUT Sequence specifies a (potentially non-linear) conversion from the output of the (conceptual) Modality LUT values to the input to the (conceptual) Presentation LUT.

If multiple Items are present in VOI LUT Sequence (0028,3010), only one shall be applied. Multiple Items indicate that multiple alternative views should be presented.

If any VOI LUT Attributes are included by an Image, a Window Width and Window Center or the VOI LUT Table, but not both, shall be applied to the Image for display. Inclusion of both indicates that multiple alternative views should be presented.

The three values of LUT Descriptor (0028,3002) describe the format of LUT Data (0028,3006).

The first value is the number of entries in the lookup table.

The second value is the first stored pixel value mapped. This pixel value is mapped to the first entry in the LUT. All image pixel values less than the first value mapped are also mapped to the first entry in the LUT Data. An image pixel value one greater than the first value mapped is mapped to the second entry in the LUT Data. Subsequent image pixel values are mapped to the subsequent entries in the LUT Data up to an image pixel value equal to number of entries + first value mapped - 1 that is mapped to the last entry in the LUT Data. Image pixel values greater than number of entries + first value mapped are also mapped to the last entry in the LUT Data.

The third value specifies the number of bits for each entry in the LUT Data (analogous to "bits stored"). It shall be between 10-16. The LUT Data shall be stored in a format equivalent to 16 "bits allocated" and "high bit" equal to "bits stored" - 1. The third value conveys the range of LUT entry values. These unsigned LUT entry values shall range between 0 and 2n-1, where n is the third value of the LUT Descriptor.

Note

  1. The third value is restricted in the VOI LUT Module to 8 or 16 but is specialized here.

  2. The first and second values are not specialized and are the same as in the VOI LUT Module.

LUT Data (0028,3006) contains the LUT entry values.
