Name: Channel Description Code Sequence
Keyword: ChannelDescriptionCodeSequence
Tag: (0022,001A)
Value Representation: SQ
Value Multiplicity: 1
  • Described in the contexts: as follows:
    Attribute Name: Channel Description Code Sequence
    Type: 3
    Attribute Description:

    Describes the light color used for each channel to generate the image.

    If Photometric Interpretation (0028,0004) has one of the YBR values, the meaning is for pixel data in an equivalent RGB encoding.

    Note

    Interpretation and representation of RGB images rely on the assumption that the red channel really contains the red wavelength range of illumination light, the blue channel the blue wavelength range, etc. Some modalities use the RGB Photometric Interpretation as a container representing 3 channels of any illumination wavelength.

    Shall have the same number of Items as the value of Samples per Pixel (0028,0002). The channels shall be described in the order in which the channels are encoded.


  • Described in the contexts: as follows:
    Attribute Name: Channel Description Code Sequence
    Type: 1C
    Attribute Description:

    Describes the light color used for each channel to generate the image. Required if this differs from the natural interpretation.

    Note

    Interpretation and representation of RGB images rely on the assumption that the red channel really contains the red wavelength range of illumination light, the blue channel the blue wavelength range, etc. Some modalities use the RGB Photometric Interpretation as a container representing 3 channels of any illumination wavelength.

    Shall have the same number of Items as the Value of Samples per Pixel Used (0028,0003) if present, or otherwise the value of Samples per Pixel (0028,0002). The channels shall be described in the order in which the channels are encoded.


  • Described in the contexts: as follows:
    Attribute Name: Channel Description Code Sequence
    Type: 1C
    Attribute Description:

    Describes the light color sensed for each channel to generate the image.

    Required if this differs from the natural interpretation.

    Note

    1. For MONOCHROME2, the natural interpretation is the full visible light spectrum. A full spectrum sensor may be presented with light of only a single color based on illumination and filters.

    2. Equipment may use a color Photometric Interpretation (RGB, YBR) as a container representing up to 3 channels of any detected wavelength.

    Shall have the same number of Items as the value of Samples per Pixel Used (0028,0003) if present, or otherwise the value of Samples per Pixel (0028,0002). The channels shall be described in the order in which the channels are encoded.
