Slide Coordinates Module Attributes
Attribute Name Tag Type Attribute Description
Image Center Point Coordinates Sequence (0040,071A) 2 The coordinates of the center point of the Image in the Slide Coordinate System Frame of Reference. Zero or one Item shall be included in this Sequence. See for further explanation.
>X Offset in Slide Coordinate System (0040,072A) 1 The X offset in millimeters from the Origin of the Slide Coordinate System. See .
>Y Offset in Slide Coordinate System (0040,073A) 1 The Y offset in millimeters from the Origin of the Slide Coordinate System. See .
>Z Offset in Slide Coordinate System (0040,074A) 2 The Z offset in microns from the image substrate reference plane (i.e., utilized surface of a glass slide).
Slide Coordinates Attribute Descriptions
Image Center Point Coordinates Sequence ... depicts the Z-axis center point location. The X-axis value of Image Center Point LocationCoordinates Sequence (0040,073A)(0040,071A) shall increase from the Origin toward the Right Edge in Reference Slide Orientation. The Y-axis value of Image Center Point LocationCoordinates Sequence (0040,073A)(0040,071A) shall increase from the Origin toward the Label Edge in Reference Slide Orientation. The Z-axis value of Image Center Point LocationCoordinates Sequence (0040,073A)(0040,071A) shall be nominally referenced as zero at the image substrate reference plane (i.e., the top surface of a glass slide) and shall increase in a positive fashion coincident with increased distance from the substrate surface. Alternatively, since WSI uses the X, Y and Z attributes but not the enclosing sequence: depicts the Z-axis center point location. The X-axis value of Image Center Point Location (0040,073A) X Offset in Slide Coordinate System (0040,072A) shall increase from the Origin toward the Right Edge in Reference Slide Orientation. The Y-axis value of Image Center Point Location (0040,073A) Y Offset in Slide Coordinate System (0040,073A) shall increase from the Origin toward the Label Edge in Reference Slide Orientation. The Z-axis value of Image Center Point Location (0040,073A) Z Offset in Slide Coordinate System (0040,074A) shall be nominally referenced as zero at the image substrate reference plane (i.e., the top surface of a glass slide) and shall increase in a positive fashion coincident with increased distance from the substrate surface.
