Table C.7.6.25-1 specifies the Attributes of the Double Floating Point Image Pixel Module. This Module differs from the Section C.7.6.3 Image Pixel Module in that:
instead of integer stored pixel values, double float stored pixel values are used
Bits Stored (0028,0101) and High Bit (0028,0102) are not used because the stored pixel values always occupy the entire word
Pixel Representation (0028,0103) is not used because the stored pixel values are always signed
Table C.7.6.25-1. Double Floating Point Image Pixel Module Attributes
Number of samples (planes) in this image. See Section C.7.6.3.1.1 for further explanation. |
|||
Number of bits allocated for each pixel sample. Each sample shall have the same number of bits allocated. See PS3.5 for further explanation. |
|||
A data stream of the pixel samples that comprise the Image. The order of pixels encoded for each image plane is left to right, top to bottom, i.e., the upper left pixel (labeled 1,1) is encoded first followed by the remainder of row 1, followed by the first pixel of row 2 (labeled 2,1) then the remainder of row 2 and so on. |
|||
Ratio of the vertical size and horizontal size of the pixels in the image specified by a pair of integer values where the first value is the vertical pixel size, and the second value is the horizontal pixel size. Required if the aspect ratio values do not have a ratio of 1:1 and the physical pixel spacing is not specified by Pixel Spacing (0028,0030), or Imager Pixel Spacing (0018,1164) or Nominal Scanned Pixel Spacing (0018,2010), either for the entire Image or per-frame in a Functional Group Macro. See Section C.7.6.3.1.7. |
|||
One limit (inclusive) of a range of pixel values used in an image to pad to rectangular format or to signal background that may be suppressed. See Section C.7.6.25.1. |
|||
Pixel value that represents one limit (inclusive) of a range of padding values used together with Double Float Pixel Padding Value (0028,0123). Required if Double Float Pixel Padding Value (0028,0123) is present. See Section C.7.6.25.1. Note
|
Double Float Pixel Padding Value (0028,0123) and Double Float Pixel Padding Range Limit (0028,0125) may specify any valid [IEEE 754] value, including NaN (Not a Number) and infinity values.
If using [IEEE 754] NaN values, it is recommended to set the sign bit to 0 and the is_quiet bit to 1. The range of NaN bit combinations under this recommendation is 7FF8000000000000H through 7FFFFFFFFFFFFFFFH.
