A Segmentation Type (0062,0001) of BINARY indicates the segmented property is present with a value of 1 and absent with a value of 0.
For a Segmentation Type (0062,0001) of FRACTIONAL the segmented property is defined as a value from zero to the Maximum Fractional Value (0062,000E). A FRACTIONAL segmentation shall be further specified via Segmentation Fractional Type (0062,0010).
Enumerated Values of Segmentation Fractional Type (0062,0010):
Defines the probability, as a ratio of the pixel value to the Maximum Fractional Value, that the segmented property occupies the spatial area defined by the voxel.
Defines the proportion of the pixel volume occupied by the segmented property as the ratio of the pixel value to the Maximum Fractional Value.
Binary Segmentation Instances may be transformed into or from "label maps", in which each pixel contains a coded value that indicates the segment, rather than the Segmentation IOD representation that encodes separate bit planes for each segment. This conversion is facilitated by knowing whether or not any segment biplanes overlap. A Segments Overlap (0062,0013) value of NO indicates they can be converted into (or may have been converted from) a label map representation without the need to check every pixel.
