|
Lossy Image Compression Method |
(0028,2114) |
1C |
A label for the lossy compression method(s) that have been applied to this image. Required if present in the source images or this IOD instance has been compressed. See Section C.8.20.2.2. |
|
Segmentation Type |
(0062,0001) |
1 |
The type of encoding used to indicate the presence of the segmented property at a pixel/voxel location. Enumerated Values:
See Section C.8.20.2.3. |
|
Segmentation Fractional Type |
(0062,0010) |

|
Maximum Fractional Value |
(0062,000E) |
1C |
Specifies the value that represents 100%. There shall be no values in Pixel Data (7FE0,0010) greater than this value. Required if Segmentation Type (0062,0001) is FRACTIONAL. |
|
Segment Sequence |
(0062,0002) |

>Recommended Display Grayscale Value |
(0062,000C) |
3 |
A default single gray unsigned value in which it is recommended that the maximum pixel value in this segment be rendered on a monochrome display. The units are specified in P-Values from a minimum of 0000H (black) up to a maximum of FFFFH (white). NoteThe maximum P-Value for this Attribute may be different from the maximum P-Value from the output of the Presentation LUT, which may be less than 16 bits in depth. |
|
>Recommended Display CIELab Value |
(0062,000D) |
3 |
A default triplet value in which it is recommended that segment be rendered on a color display. The units are specified in PCS-Values, and the value is encoded as CIELab. See Section C.10.7.1.1. |
As a consequence of the enumerated Bits Allocated and Bits Stored attribute values, single bit pixels shall be packed 8 to a byte as defined by the encoding rules in PS3.5.
