Name: Presentation Pixel Spacing
Keyword: PresentationPixelSpacing
Tag: (0070,0101)
Value Representation: DS
Value Multiplicity: 2

• Described in the contexts:
  • Displayed Area Module > Displayed Area Selection Sequence > Presentation Pixel Spacing
  as follows:
  Attribute Name: Presentation Pixel Spacing
  Type: 1C
  Attribute Description:

  Physical distance between the center of each pixel in the referenced image (before spatial transformation), specified by a numeric pair - adjacent row spacing (delimiter) adjacent column spacing in mm. See DICOM Standard Part 3 - Section 10.7.1.3 for further explanation of the value order.

  1. This value may be different from Pixel Spacing (0028,0030) or Imager Pixel Spacing (0018,1164) specified in the referenced image, which are ignored, since some form of calibration may have been performed (for example by reference to an object of known size in the image).

  2. If the row and column spacing are different, then the pixel aspect ratio of the image is not 1:1.

  Required if Presentation Size Mode (0070,0100) is TRUE SIZE, in which case the values will correspond to the physical distance between the center of each pixel on the display device.

  May be present if Presentation Size Mode (0070,0100) is SCALE TO FIT or MAGNIFY, in which case the values are used to compute the aspect ratio of the image pixels.
