The Enumerated Values of Photometric Interpretation (0028,0004) shall be:
Note: There is no formal color space defined, hence “false” color applications that encode near-visible light images may be encoded, for example, as RGB.
The Enumerated Value of Bits Allocated (0028,0100) shall be 8; the Enumerated Value of Bits Stored (0028,0101) shall be 8; and the Enumerated Value of High Bit (0028,0102) shall be 7.
The Enumerated Value of Pixel Representation (0028,0103) shall be 0.
The Enumerated Values of Samples per Pixel (0028,0002) shall be as follows: If the value of Photometric Interpretation (0028,0004) is MONOCHROME2, then the Enumerated Value of Samples per Pixel (0028,0002) shall be one (1). If the value of Photometric Interpretation (0028,0004) is RGB or YBR_FULL_422 or YBR_PARTIAL_420 or YBR_RCT or YBR_ICT, then the Enumerated Value of Samples per Pixel (0028,0002) shall be three (3).
If present, the Enumerated Value of Planar Configuration (0028,0006) shall be 0. This value shall be present if Samples per Pixel (0028,0002) has a value greater than 1.
The Image Type attribute identifies important image characteristics in a multiple valued data element. For Visible Light, Image Type is specialized as follows:
a. Value 1 shall identify the Pixel Data Characteristics in accordance with Section C.22.214.171.124.2; Enumerated Values are: ORIGINAL and DERIVED;
b. Value 2 shall identify the Patient Examination Characteristics in accordance with Section C.126.96.36.199.2; Enumerated Values are: PRIMARY and SECONDARY.
c. Value 3 may be absent, but if present shall identify the members of a stereo pair, in which case Referenced Image Sequence (0008,1140) is used to identify the other member of the pair. If present, the Enumerated Values are:
|STEREO L||Image is the left image (relative to the observer's left) of a stereo pair acquisition;|
|STEREO R||Image is the right image (relative to the observer's right) of a stereo pair acquisition.|
d. Other Values are implementation specific (optional).
When Image Type (0008,0008) Value 3 is STEREO L or STEREO R, Referenced Image Sequence (0008,1140) shall be used to identify the corresponding SOP Instance of the Stereoscopic acquisition. In this case, either:
only a single item shall be present, or
multiple items may be present, each with the Purpose of Reference Code Sequence (0040,A170) present, and only the first item having the Purpose of Reference value (121315, DCM, “Other image of stereoscopic pair”).
