This Module describes equipment used to create original images.
Table C.8.17.3-1. Ophthalmic Photographic Parameters Module Attributes
Nominal pass-through wavelength of light path filter in nm, or wavelength of a monochromatic (e.g., laser) light source. Required if Acquisition Device Type Code Sequence (0022,0015) is (1362124004, SCT, "FLIO"). May be present otherwise. |
|||
Pass band of light path filter in nm. This Attribute has two Values. The first is the shorter and the second the longer wavelength relative to the peak. The values are for the - 3dB nominal (1/2 of peak) pass through intensity One of the two Values may be zero length, in which case it is a cutoff filter. |

The values are for the - 3dB nominal (1/2 of peak) pass through intensity One of the two Values may be zero length, in which case it is a cutoff filter.

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