• All Image Instances shall have the same values of

  • SOP Class UID(0008,0016)

  • Series Instance UID (0020,000E)

  • Frame of Reference UID (0020,0052) or Volume Frame of Reference UID (0020,9312)

• All Instances or frames shall have the following Attributes of the same value:

  • Samples per Pixel (0028,0002)

  • Photometric Interpretation (0028,0004)

  • Rows (0028,0010)

  • Columns (0028,0011)

  • Bits Allocated (0028,0100)

  • Bits Stored (0028,0101)

  • High Bit (0028,0102)

  • Pixel Representation (0028,0103)

  • Pixel Spacing (0028,0030)

• Photometric Interpretation (0028,0004) shall be MONOCHROME2

• Pixel Data (7FE0,0010) is present.

• All Instances or Frames have orthogonal row and column vectors

• A VOLUME input shall have more than one frame.

• No two Instances or Frames share the same Image Position (Patient) (0020,0032) or Image Position (Volume) (0020,9301). Two Instances or Frames should be treated as sharing the same position if the differences between their positions is sufficiently small.

• All Instances or Frames shall be parallel. Instances or Frames may be treated as parallel if the differences in their Image Orientation (Patient) (0020,0037) or Image Orientation (Volume) (0020,9302) are sufficiently small.

• All Instances or Frames shall be sufficiently aligned such that a single ray can pass through the upper-left hand corner of all Instances or Frames. That ray shall be orthogonal to the plane of the frame (i.e., normal to the input frames). Instances or Frames may be treated as aligned if the degree of misalignment between frames or relative to the normal is sufficiently small.

• A VOLUME input may have:

  • Variable spacing between slices

  • Overlapping slice thicknesses

  • Gaps between slice thicknesses

Note

The degree of tolerance for discrepancies in position and orientation may vary between applications.
