SSS Use of Image Libraries in SR Documents (Informative)

This Annex contains examples of the use of Image Library templates within SR Documents.

SSS.1 Image Library for PET-CT Example

This PET-CT example dillustrates an Image Library in which Attributes of images for two modalities are described, with common Attributes factored out of the individual image references.

Note

  1. Only the Attributes of relevance to SUV and spatial measurements are included, not a complete description of all aspects of acquisition.

  2. Only two images for each modality are described, rather than all slices acquired, since it is usually only necessary to describe images that are referenced elsewhere in the SR content tree, e.g., on which a region of interest is specified from which measurements are made.
