Table C.8.12.14-1 specifies the Attributes of the Microscope Slide Layer Tile Organization Module, which describe the logical and physical organization of the tiles within a single resolution layer encoded as a tiled Image, such as that of a Multi-Resolution Pyramid.
Table C.8.12.14-1. Microscope Slide Layer Tile Organization Module Attributes
Total number of columns in pixel matrix; i.e., width of total imaged volume in pixels. See Section C.8.12.14.1.1 |
|||
Total number of rows in pixel matrix; i.e., height of total imaged volume in pixels. See Section C.8.12.14.1.1 |
|||
Total number of focal planes (Z locations) in the pixel matrix; i.e., depth of total imaged volume in pixels. See Section C.8.12.14.1.1 Required if Dimension Organization Type (0020,9311) is present with a value of TILED_FULL. May be present otherwise. |
|||
Location of pixel 1\1 of the total pixel matrix in the Slide Coordinate System Frame of Reference. Only a single Item shall be included in this Sequence. See Section C.8.12.14.1.2 and Section C.8.12.2.1.1 for further explanation. |
|||
The X offset in millimeters from the Origin of the Slide Coordinate System. |
|||
The Y offset in millimeters from the Origin of the Slide Coordinate System. |
|||
The Z offset in µm from the image substrate reference plane (i.e., utilized surface of a glass slide). Required if the Z offset is not zero. May be present otherwise. |
|||
The direction cosines of the first row and the first column of the total pixel matrix with respect to the Slide Coordinate System Frame of Reference. See Section C.8.12.14.1.2. Required if Plane Position (Slide) Sequence (0048,021A) is present within a Functional Group Sequence or Dimension Organization Type (0020,9311) is present with a value of TILED_FULL. May be present otherwise. |
Total Pixel Matrix Columns (0048,0006), Total Pixel Matrix Rows (0048,0007) and Total Pixel Matrix Focal Planes (0048,0303) describe the size of the entire imaged volume as a single extent across all frames (tiles).
The extent would be as described in these Attributes if the whole volume would be imaged and encoded as a non-sparse pixel matrix with the pixel spacing as specified in Pixel Spacing (0028,0030) of the Pixel Measures Functional Group (see Section C.7.6.16.2.1), such as when Dimension Organization Type (0020,9311) is present with a value of TILED_FULL.
Total Pixel Matrix Origin Sequence (0048,0008) specifies the location of the top leftmost pixel of the pixel matrix, and Image Orientation (Slide) (0048,0102) specifies the direction cosines of the first row and the first column of the pixel matrix, both with respect to the Slide Coordinate System Frame of Reference (see Section C.8.12.2). Although the image acquisition may vary the true row and column orientation at the pixel scale to account for local variation in the physical specimen, this Attribute describes the orientation as if the Pixel Matrix were flat.
