C.7.6.25 Double Floating Point Image Pixel Module

Table C.7.6.25-1 describes the Double Floating Point Image Pixel Module. This Module differs from the Section C.7.6.3 Image Pixel Module in that:

Table C.7.6.25-1. Double Floating Point Image Pixel Module Attributes

Attribute Name

Tag

Type

Attribute Description

Samples per Pixel

(0028,0002)

1

Number of samples (planes) in this image. See Section C.7.6.3.1.1 for further explanation.

Photometric Interpretation

(0028,0004)

1

Specifies the intended interpretation of the pixel data.

Enumerated Values:

MONOCHROME2

Rows

(0028,0010)

1

Number of rows in the image.

Columns

(0028,0011)

1

Number of columns in the image.

Bits Allocated

(0028,0100)

1

Number of bits allocated for each pixel sample. Each sample shall have the same number of bits allocated. See PS3.5 for further explanation.

Enumerated Values:

64

Double Float Pixel Data

(7FE0,0009)

1

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.

Pixel Aspect Ratio

(0028,0034)

1C

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.

Double Float Pixel Padding Value

(0028,0123)

3

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.

Double Float Pixel Padding Range Limit

(0028,0125)

1C

Pixel value that represents one limit (inclusive) of a range of padding values used together with Float Pixel Padding Value (0028,0122).

Required if Double Float Pixel Padding Value (0028,0123) is present.

Note

  1. If only a single padding value rather than a range is required, then both Double Float Pixel Padding Value (0028,0123) and Double Float Pixel Padding Range Limit (0028,0125) will contain the same value.

  2. The general considerations described in Section C.7.5.1.1.2 may be helpful in understanding the corresponding floating point Attributes, but are not normative.
