C.8.12.1.1 VL Image Module Attribute Descriptions​

C.8.12.1.1.1 Photometric Interpretation​

Enumerated Values:​

MONOCHROME2​

RGB​

YBR_FULL_422​

YBR_PARTIAL_420​

YBR_RCT​

YBR_ICT​

Photometric Interpretation (0028,0004) shall be RGB for uncompressed or lossless compressed Transfer Syntaxes that do not have​ defined color space transformations, YBR_ICT for irreversible JPEG 2000 Transfer Syntaxes, YBR_RCT for reversible JPEG 2000​ Transfer Syntaxes, YBR_PARTIAL_420 for MPEG2, MPEG-4 AVC/H.264 and HEVC/H.265 Transfer Syntaxes and YBR_FULL_422​ for JPEG lossy compressed Transfer Syntaxes.​

Note​

1.​The YBR_FULL Photometric Interpretation (0028,0004), such as might be used with the RLE Transfer Syntax, is not​ permitted.​

2.​There is no formal color space defined, hence "false" color applications that encode near-visible light images may be​ encoded, for example, as RGB.​

C.8.12.1.1.5 Planar Configuration​

This value shall be present if Samples per Pixel (0028,0002) has a value greater than 1.​

Enumerated Values:​

C.8.12.1.1.6 Image Type​

The Image Type Attribute identifies important image characteristics in a multiple valued Data Element. For Visible Light, Image Type​ is specialized as follows:​

•​Value 1 shall identify the Pixel Data Characteristics in accordance with Section C.7.6.1.1.2.​

Enumerated Values:​

ORIGINAL​

DERIVED​

•​Value 2 shall identify the Patient Examination Characteristics in accordance with Section C.7.6.1.1.2.​

Enumerated Values:​

PRIMARY​

SECONDARY​

•​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.​

Enumerated Values:​

STEREOL​Image is the left image (relative to the observer's left) of a stereo pair acquisition​

STEREO​ Image is the right image (relative to the observer's right) of a stereo pair acquisition​

R​

•​Other Values are implementation specific (optional).​

C.8.12.1.1.7 Referenced Image Sequence​

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​

- Standard -​

•​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").​

C.8.12.2 Slide Coordinates Module​

The table in this Section contains Attributes that describe Slide Coordinates. Slide Coordinates provide a means to locate an image​ within a given Frame of Reference.​

Note​

1.​A Frame of Reference (identified by a Frame of Reference UID) typically only applies to a single mounting of a slide on​ aparticularmicroscopestage;thereisnoguaranteethatasubsequentmountingoftheslide,evenonthesameequipment,​ willallowreproduciblepositioningtotheexactsamelocation.TheseAttributesallowconsistentlocationofmultipleimages​ within the Series of a single Frame of Reference.​

2.​There is no a priori correspondence of pixels to Slide Coordinates. Therefore, the geometrical symmetry point through​ the pixel plane of the digital microscope may not correspond to the center of a pixel. The geometrical symmetry point​ could be between pixels.​

3.​This Module formerly included a Type 3 Attribute Pixel Spacing Sequence (0040,08D8), and subsidiary Attributes; see​ PS3.3-2009. Pixel Spacing is an Attribute of the image acquisition, not the slide coordinates, and is inappropriate for​ this Module. It is now conveyed by Pixel Spacing (0028,0030) in the VL Image Module or the Pixel Measures Functional​ Group (see Section C.7.6.16.2.1).​

C.8.12.2.1 Slide Coordinates Attribute Descriptions​

C.8.12.2.1.1 Image Center Point Coordinates Sequence​

This Section defines the Slide Coordinate System and specifies the Attributes that shall be used to describe the location of the center​ point of the Image pixel plane (as captured through a microscope) in the Slide Coordinate System Frame of Reference.​

Note​

In Slide Microscopy (SM), the Microscope is equipped with a moveable Stage and position sensors that enable storage of​ the location of the center point of the displayed image with respect to the examined Specimen.​

The Stage is the part of the Microscope to which the Slide is attached for viewing. The Objective Lens is the lens that is closest to​ the Specimen. The Top Surface of the Slide is the surface of the Slide on which the Specimen is mounted. The Bottom Surface of​ theSlideistheoppositesurface.ThisSpecificationpresumesthat:1)theSlideisrectangular;2)theTopSurfaceoftheSlideisoriented​ toward the Objective Lens of the Microscope; and 3) the Bottom Surface of the Slide is in perfect contact with the Microscope Stage​ when the Slide is attached to the Stage for viewing.​
